The scenario being bugged means he can't play Resto?? Ok man
Anyway having done all 12 class campaigns, they're really nothing to write home about. The only one I even remember anything from is the DK one. They all follow the same general outline of: do some quests out in the world, click to recruit some followers, run a bunch of dungeons, do 20 world quests. Wow, so immersive! If Blizzard had actually followed through on compelling class stories, sure I'd be sad to see them go. But they haven't.
