Right, so I'm gonna attempt one of these for funsies.
1.ReHaB: Currently holds the top spot. Good average points, large amount of villas. They're neck in neck with LoL for points. They also have the highest ODA, so they're kicking the necessary parts to pull out as a dominant tribe. They recruited some good players when the likes of SHAC and GODS crumbled, but I don't know if the leadership will be able to make good use of their potential. I'll ignore the rumours about them and ADDICT, since a proper statement was never really issued. I also see one or two players within their ranks that are known to be mediocre, which they have neglected to kick, which means either they know something we don't, or their standard of player isn't as high as it should be. These guys are going to be around for a long time, no large flaws here. FAF are likely to cause them trouble, although nothing they can't handle.
2. LoL: My own tribe. Even from an unbiased point of view, these guys look good. High average points, excellent K domination. People probably complain about the amount of internals we've had, but it's freed up room to recruit local players with potential, which we've done to good effect. From an insider's point of view, leadership is like no other. Highly organised, and the willingness to commit to ops, from top to bottom, is astounding. I think we have quite a good shot at winning the world.
3. ADDICTS: Formerly ReHaB 2, these guys are rumoured to have connections with TFF on UK3 (unless I misheard, lol). They're quite far behind LoL and ReHab, but not any less of a threat to the tribes around them. They're one of the four K leaders, so will probably do well. They have LoL to their south and ReHaB to their east. Assuming they have a level of cooperation with ReHaB (NAP would suffice), they could become a pain for LoL. They have DOGS in their backyard to deal with first though, which could be a problem. DOGS are known for having high OD, so they're not going to go down without a fight, and this could cripple them should LoL take advantage. Again, I'd expect this tribe to last a while longer, but perhaps not to the end-game.
4. T.E.A: Another tribe from UK1, these guys have the lead in K55, and don't look like they're going to lose it. They have ReHaB to their north and LoL to their west, so they're caught between a rock and a hard place. SWARM, more UK1 veterans, are the biggest threat in their K, with only 55k points difference between them. They seem to have a good solid spread on the map, and are lead well, but I think they're in a similar position to ADDICT, in that if SWARM weaken them sufficiently, Lol or ReHaB could take advantage and move into the K. Don't confuse that with saying there won't be resistance though, as I expect T.E.A to be around for quite some time too. Not end-game material, but a force not to be trifled with lightly.
5. FAF: I will admit I don't know as much as I should about these guys. They have gotcha, who is currently the top ranked player on the world. No doubt, they have a few good names in there, but I can't see them managing to last past summer. They're in ReHaB's K, so they have a very strong tribe to contend with right from the start. I'm going to be horrible presumptuous here and say that I needn't write much more about them. They are going to be a royal pain in ReHaB's side, but nothing more. It's not their fault, they're just in the wrong place at the wrong time. If some of the better players merge into ReHaB accounts, they (as individuals) could do quite well, but that depends on whether ReHaB wants them or not. At any rate, ReHaB is full up, and may not have accounts needing co-players at this stage.
6. Wolves: Wolves have a nice position in the core, which is both an advantage and disadvantage. LoL, ADDICT and ReHaB form a ring around them, which could prove to be a tightening noose. The fact that they were involved (allegedly) with USSR at the start of the world implies they may have poor judgement. These guys won't last, because they're in 3 Ks at once. They're going to be fighting too many of the big tribes at once, which they're simply not strong enough to pull off. They have a low average points compared to LoL and Rehab, and still the lowest in the top 7. I doubt there will be any big war here, LoL and ADDICT will simply chip away at them, with ReHaB grabbing a few villas here and there as well.
7. SWARM: As far as I know, this tribe is based around UK1 players, some of which I've played with and aren't a fan of. They're in an awkward position, with the bulk of their players wrapping around T.E.A, spreading into K54. The rest lie to the north, where ReHaB are sure to swoop down on them. Their average points is above Wolves, and they're the last tribe with any kind of potential imo. However, I still feel that that potential is limited to how much of a pain they can be to the surrounding tribes before they're wiped out. Like with many of the top 10 tribes they don't have a K to call their own, so that leaves them targets for multiple larger tribes.
8. DOGS: These guys are a fighting tribe, very high OD. Will that help them? Not one bit, I suspect. ADDICT are their main problem at the moment, but I doubt they'll last long enough to have to fight LoL or ReHaB. They'll go down fighting, but will lose K44 as ADDICT slowly secure it as their own. Getting involved in fighting so early on has clearly weakened them, and it may just have been their downfall, ultimately. They're on the way out.
9. ~USSR~: The remnants of what they once were, most of the better players seem to have left for better pastures. They've been the subject of constant criticism from day one. Poor leadership and sheepish players have not done them any favours, and they're on the decline. They have ReHaB to contend with as an immediate threat, an encounter which they're sure to succumb to. Imo, the best thing that they could do is disband and declare every man for themselves, and hope that some of their players find homes in other tribes. This will be the first tribe out of the current top 10 to go.
10. A.F.A: This is the tribe who largely attributed to the downfall of GODS, as far as rumours go. While some former GODS players state that they were not beating them, they certainly managed to weaken Cannabinoid, who was once a major player on the world. This tribe has risen in the last week or two, and has shown a level of competency in fighting. Positioning-wise, they have SWARM and T.E.A to deal with. If they teamed up with SWARM, they may just have a chance of taking down T.E.A. However, I don't feel this will happen, as several former GODS players have joined SWARM and will probably want blood. They also have TAL in their immediate vicinity, and while TAL aren't in the top 10, they do have more strength within K55. If they could join up with SWARM and/or TAL, maybe they could take on T.E.A, but I don't think any of the three tribes could organise that properly, hence they're doomed to be targets for the K leaders, as are the majority of the top 20 tribes. As with DOGS, I fully expect these guys to go down fighting.
Overview: I think the end-game is going to be between LoL and ReHaB. Once the four K leaders have secured satisfactory K domination, I suspect that ReHaB will expand to the south to take on T.E.A, while LoL move to the north to take on ADDICT. If ReHaB and ADDICT form an alliance, LoL and T.E.A may be forced to do the same to survive. And the reason why I link LoL and T.E.A is that there is already a link between ReHaB and ADDICT, whereas I can't imagine ADDICT teaming up with LoL, or ReHaB teaming up with T.E.A. I think that K domination will be achieved over summer, perhaps in July or early August. LoL will be first to achieve this, followed by ReHaB, then ADDICT and finally T.E.A. I can't see this world growing beyond the four core Ks, so I imagine it will only last around a year. In Autumn, there will most likely be an east/west divide (between ReHaB and LoL). Any number of things could change between now and then, so I can't 100% predict a winner. However, with all the information at my disposal, and if I had to put down money on the UK12 winners, I'd say it will be LoL, as they have already won UK7 (as KnK). The main advantage that LoL currently have over ReHaB is that the players already know each other well and cooperate fully. Now, in the end, I would assume that both tribes would have a similar level of internal cooperation, however LoL have the early advantage, and may build up a lead with that. I think LoL have the edge on this world, which will ultimately allow them to win. ReHaB will (hopefully) put up a challenge though, due to the small nature of the world.
I hope I haven't offended anyone with my view of the world so far, as I tried my best to remain unbiased!
