Not this, please... I know that everyone want to play the game as they like. But let any single player able to be self sufficient can kill any game. Look at Darkfall, everybody can craft everything, can fight in any style they like. It ended in no commerce at all (apart a little buch of items like rare ores and taints of khamset) where the more you play the more you win. We already have this situation in Xsyon, a single player can be a master bonecrafter, build his own fortress, craft his vhq blade and so on. The result is that everyone is in theyr homestead/tribe with no need to go around exploring and the game feels more empity than it actual is.
I think we need, and soon, a skill decay/cap/anything to put diversity in game. A master leathercrafter shouldn't be able to be a master toolcrafter as well. If he needs any tool to craft an armor he can join a tribe or trade with other players. And honestly, i would love something arsher. A master leatercrafter should craft just one high set and to learn his set he should forget how to craft, for example, leater straps (at least of good quality). In this way you have 2 sub professions in leathercraft: the one to craft armor and the one to model raw leather, both valuable profession. Or a third one, the leatercrafter who can do both but limited to middle class armors (still a good choice since he can sell to new players). But really, i know that this last idea can be too much for the majority of players.
But, back on topic, let people be self sufficient can kill the game in few months. And from what i remeber devs are against this possibility (expecially the killing one i guess :P ).
And about the two servers/two areas, mine was not a solution. If it was that easy to solve the problem we were not talking about that now
