Since I have yet to be in a guild in ANY MMO that didn't have issues with drama and bias towards certain people over others no matter how much you've done for them just make it unappealing for me.

It's simply not worth it, plus queue times are the same solo as they are with a pre-made group, so with that being the case why bother with a FC? Easier to just find a group in /shout and just go when I feel like going rather than waiting for specific people in a FC to stop screwing around and start a group.
