Okay, Blizzard. I admit it. You got me.
I'm resubbing as soon as I build my new computer next month(old one's HDD has nowhere near enough space for the task). I've got everything since Cata to play through. Probably be the most hardcore casual ever in an effort to get up to the new stuff. Seriously doubt I'll do much in the way of raiding or whatnot, but it'll be fun to play through the story. Maybe roll up a new character to see what's been changed at the lower levels.
