I'm a pretty big WoW fan, but even I've gotta say XBL. You said you want to reroll a new toon, but without someone to run with, it can get pretty boring and isolated. Might just be my server, but I recently tried rolling a druid, and I can go for hours without seeing another friendly player. Not to mention, compared to questing in BC or WotLK, question in WoW classic just sucks. You'll have quests that ask you to travel to other sides of zones, or entirely different zones, or an entirely different continent altogether. Really, if you want to roll a new toon, wait until Cataclysm comes out.
