1. Comparing Warlocks, Mages, and SPriests, which would you say has the most fun or interesting DPS rotation? By this I mean, has to watch for procs; a good rotation v. a bad rotation means a significant DPS difference; isn't spamming one or two buttons the entire boss fight (i.e Arcane Mages).
2. Which class brings the most added utility? I.E. SPriest off-specc'ing for healing; mages for CC, portals, Intellect Buff; Warlocks for summons, soul stones; etc.
3. Which class is very rewarding to play in PvP? I don't necessarily want the OP 2-shot class, but I would like to have one that has a learning curve and (similar to DPS) there is a difference between a good and bad player.
4. And finally, which one makes me look more leet and will add significant inches to my E-Peen? (I kid....)
Thanks for your help!
