I'm still iffy about this topic. In one way, for the interests of keeping PvP as strong as possible, especially for ques, I think removing GC's would be a good thing. There's a lot of pro's to it, honestly.

1. You'd be able to buddy up with friends in a different GC.

2. Que times would surely increase.

3. GC grudge matches would ... not be eliminated, but more than likely replaced by specific premade group rivalries, which I guess is healthier.

4. In the interests of winning, players would be more encouraged to form pre-mades and join PvP LS.

That being said, there are a few things that bother me about it. Someone else pointed out that it's nice to have a sense of belonging to a team, and I agree with that. There's a lot of crap players and noobs in my GC, but I still enjoy seeing familiar faces from different servers. Removing GC restrictions would effectively cut us off from one another, unless you solo qued and got really lucky.

Another thing is pre-made themselves. There's been a lot of chatter about Pre-made groups que dodging and leaving entire alliances empty. I can see this problem, or one similar, happening if GC's are gone. IF the removal of GC's encouraged more players to form premades, the DF might have trouble balancing the solo que'ers. They might get shafted into sparsely populated teams, facing down highly coordinated full teams, and that would be very unfair, especially to those who come from servers with very small pvp communities... though, that might not make a huge difference compared to how it is now. It's hard to say if a stronger pre-made community would be a good thing or not. We probably won't know for sure until it happens ... if it happens.
