Good find! This is definitely good news if the industry MMO leader just decided to make this change. I'm very interested to see a follow-up from WoW players as to how this affected queue times, it's a perfect test case and should help SE decide if it makes sense to remove GC restrictions.

I've argued why we should add a similar system in the past, but this is a live experiment which will be way more meaningful than some random person trying to articulate a point on these forums. I'm pretty excited about this, thanks Plumpy!
