You missed one key word. There are to many crappy guilds. The decent guilds are few and far between. I'm really looking forward to about three months after launch.
The grinders will have quit. Most of the crappy guilds will have quit. All of the guys who get destroyed in the first couple weeks will quit saying the game is shit (I'm looking at you KGB if you even have the balls to come back since you ran away after the first alpha) Most of the guilds left will be decent to above average. Always happens in every game.
3 plus months is where conquest games really start to shine with really competitive territory wars.
luv you Dready
