Defleshed

This, exactly this! Unless you're in to pvp and lots of it what else is there but to sit idle in [insert your favorite home base]? Run UBRS although you don't need it? Grind gold(something I should to really)? Alts could be fun, but it's not fun enough to keep you interested. The hype is over.

What the horde provider of faps said

Gold!

Horde side I presume? And fun classes? It boils down to what you thinks is fun? Is it fun to get into the fray, roll melee or if you wish to stand a bit further away then roll caster-ish. All classes are fun, in their own way.

They both spam bolts in raids, mages get to buff and warlocks get to add a curse... other than that it's bolt-spam-fest! If you intend to do pvp, mages have a little better survivability than locks(imo, but then again I'm a glass cannon) and have a little better burst. Locks have a few tricks though, pets help alot. And dots can be thrown around alot. Just don't fuck with targets cc'd (that goes for every damn aoe class and hunters the most). It all comes down to if you wanna thrown ice around or dabble in shadow magic. I lost my soul to the latter.
