Reading all the suggestions mentioned, they all have their advantages and disadvantages.
Lets say for example, automatic renaming of attacks. I mean people who learnt skills (yes I consider them skills such as workingout unit types in attack, sniping, dodging, backtiming and so on) and spent months on improving them, I think it would be fair disadvantage to them if new players can come and just press a button and it would do all the hard work for them. This in long term would make this game more of a botted game rather than game that demands human analytical and mathematical skills. Which is why I enjoy this game. Skills, and learning skills thats what keeps you going.
Now to the topic of new comers being able to enjoy the game, well I feel TW help is not sufficent enough for new comers to join and then get started and keep going. I say its not enough as techniques like Farming, Sniping or other Offensive and Defensive are not explained enough. On the help pages all you get is, unit types, their attack/defense strength, farmspace and a bit about nobling, which again is not enough. There is no mention of Farming and so on. Thus that puts them in the backseat straight after joining as an experienced player would be farming at the start of the world and new player would be waiting and building up the resources. Yes, there is help available elsewhere such as Wiki and so on, why not simple in-game help has little bit more detail on tactics rather than just the basics.
Most of the in-game help screenshots are in German and/or other languages which is fine but, Its an international game so some screenshots in English would help new players more.
Now to the question on how to make this game More fun for new players in terms of attacker and defender then simply have time limit on the world. Create a world with say 8 hours a day gameplay. All players must only be able to play during those 8 hours, as most of the servers are localised such as .co.uk in terms of timezones, this shouldnt be problem.
Everything can be learnt in those 8 hours a day gameplay. Yes, it would be slow server as would only be active for 8 hours but again learning is a slow process and this would allow new players to find their feet quickly and effectively and at the same time would give break to experienced players who would be playing on that world lol.
Now 8 hours long attacks, well yes, just like nobleman's travel distance can be capped by simple coding, a limit to the attack can be applied in the same way so attacker can only attack at max distance of 8 hours.
Instead of calling it any other world, it can be named as "Tribal Wars Octa". For 8 hours gameplay I dont think many would need a co-player so it makes it even simpler. World active for 8 hours a day (with normal speed 1, 1.6) gives defenders atleast 66.6% more chance to see the attacks coming and defending against them.
EDIT: I might so add, have ALL scripts disabled (if possible), Players cant choose starting position and players cant join tribe till after week of the start of the world. Thus would give everyone pretty same grounds to start off from.
