To clarify, I don't think they're getting rid of LT and Metatopolis for 2v2, I think they're just done testing them.
Excited about the achievements, and I know a lot are excited about the map editor...but I don't think those maps will be able to be played on b.net yet?
The actual changes are kind of underwhelming. Zerg still needs a bit more buffs imo. I like the slight Protoss nerf, but I also think they need a bit more of that.
edit: Hahahaha. I canceled my order an hour ago, got a key in my email 5 minutes ago. Suck it, shitty GameStop.
