To me, the definition of 'Skill' (Based on TW, not the word itself) Skill is the ability to overcome the odds, if you will, having multiple opponents attacking, not an end in sight, Skill to me, is having everyone in one tribe working as one, supporting, whether that be in offense, defense, or even as simple as a few resources here and there.
Alot of people here, there and, well everywhere think that 'Skill' is Being rank one in this, rank one in that, yes that is correct, but in different ways wrong, maybe some tribes haven't been giving the opportunity to express this to the world, Here I'm referring to quieter tribes, who don't post much/at all on the forums to show the world of maybe achievements, Tribes like FREE, TR, *FW* and IWL.
This is a daunting question as the possibilities could go on for ages.
That is my opinion on the word 'Skill'.
