What I'm waiting for is for them to implement some sort of "matching system" that takes the surplus from one GC and shafts them into the spare spots of an empty GC. So, the first week of implementation you'll get a bunch of people who are used to spawning in as "yellow" and they'll be "blue" instead, and they'll all be like..."Whut...? -_-"

Cherry on the cake would be if they just didn't tell anyone about it, so we'd all be super confused the first few weeks wondering if we somehow glitched our GC's lol.
