Title tbh.
I want to level an alt, and I have heirlooms for all specs/classes. I have never played a Priest, a Shaman, but I have played a Paladin, it used to be my old main in BC, but it got deleted. Paladins are literally an entirely new class from mid BC, though. When I healed on my paladin, I didn't have Beacon yet, (that was the pre sunwell patch) and I just rocked Flash of LIght, HOly Light, and Holy SHock like a bawz.
So, what class between those three is FUN? I don't mean 'LIEK LRLLY GUD @DPS" or anything, I want an alt for just one thing: fun. Which has the funnest playstyle? Is shadow fun? Is ele fun? Fill me in.
Sunshine edit: I'm leaving this open despite it originally being a "what class should I play" thread because there's some really nice discussion going on here. I've broadened the title; feel free to include information from all classes.
