Let's say, i'm a member of some small guild consist of four or five active members. I don't care much about outposts, but i like PvP and battles. Now, what would i have to do if GvG become real, forced by game mechanics? I would have to quit the guild that i like to be in, leave people that i like to hang around with, and join some large guild in order to have the kind of fun that i enjoy. And the rest folks in my old guild would have to do the same. Now, THAT'S just silly.Your notion that a small guild has to quit because of that though is just silly.

There is no monopolizing. Because people tend to share their OP goods with others. At least within faction. Personally, i always got what i asked for with no problems at all. It's really a solution to combat inactive/low member guilds from monopolizing a resource
