Yeah, we get a new class every other expansion, and it's always busted as fuck. Gotta move them units.
Unfortunately for Blizzard, they fucked up with MOP and their busted new class was weird and confusing and started at level 1, so nobody played it. They learned their lesson from that though, so Demon Hunters started in spitting distance of level cap and with a 2 button dps spec to keep lil timmy happy as a pig in shit.
Cynical jokes aside, Demon Hunter is one of the absolute best feeling classes to actually play in the overworld. Great alt.
