When I saw GC use the "invalidated" word in a tweet I knew we were in for another awkward expansion.
I mean, really, who CARES that someone who didn't start playing in the first couple weeks of the expansion is able to catch up right away in the middle of the expansion? Is there someone that's actually BAD for? I don't understand what GC is trying to protect.
Blizzard got a whole bunch right with MoP, and more or less at the last moment, messed it up.
