Well, since we're assuming it would be with all end-of-life fixes in place, it was decent. It was a bad joke at launch, though - just as we friggin told them repeatedly in beta, Colossus Smash making Warriors do all of their DPS in 6 sec burst windows would be a huge problem... and it totally was! Giving Arms throwdown on top of CSmash was what really made it such an issue, though. Didn't they change CSmash to ignore some large portion of the target's armor instead of all of it? Or was that an MoP change?
Either way, I'll probably spend a few weeks playing with Cata Classic if it happens (Vashj'ir is still the coolest zone they've made and the first 2/3 of it were a great experience in general), but otherwise I'm in the MoP waiting room once WotLK has lost my interest.
