Some of our members like modding. Others like the political RP. Several of us belong to different guilds. I myself, I like to party and drink.

So it just spreads us pretty thin. We are also all pretty experienced alliance players, so finding groups is pretty easy for us. It might be harder if you are new to the game.
So let's say that we make a magic sword, and the three fighters in the group spread it around. Then we make another magic item, and the celestials share it. If someone can't go to an event, we switch it out to another player. If no one has gotten a magic item in a while, we may try and pick up a random magic item in auction and give it to that person.
We want our group to be successful but also to have good gear, so we try and spread that around.
