Another WvWvW idea. Guild Ranking
this is a very interesting idea. each world would have the top guild based on factors such as towers/camps/keeps captured, players killed, etc. with maybe extra points going towards defense. unfortunately, this would encourage zerg play, meaning zerg guilds would dominate the top positions, meaning small guilds would feel even more hopeless.
that being said, if the score scaled to how many players are in the guild (repping and present of course) when an objective is captured/ defended, then maybe your idea could work.
also, the idea of a pvp guild makes no sense to me, it seems anet wants a guild to be capable of all aspects of the game.
