in order
Hunter - you have a pet.. you can bot with VERY low gear and still come out on tops
Death Knight - you heal as you fight.. nuff said
Pally - you dish out a good damage.. + you can self heal + wear armour + take on alot of mobs at the same time
Shaman - you can self heal + once you have watershield you never run outta mana.. you can take on ALOT of mobs
Mage - you really are a glass cannon.. found to have big trouble when you get more than 1 mob.. yes you can make your own water etc.. but there is still alot of downtime while you drink it
Priest - tried for a little.. found it horrible.. downtime is just crazy
Rogue - Never tried
Warrior - Never tried
Warlock - Never tried
alot of people like to bot locks and palis
i have leveled quickly with arms warrior to 55, and then dk (blood)to 80
however i have been leveling a feral druid and that has been going
pretty quick ... after level 40 it hardly needs to drink or eat at all
with the healing. i have been RaFing this druid with a rogue leader
and my xp/hr doubled. (without the blizz xp bonus)
best of luck to you = )
The only mention I saw of priest in this thread were saying they were horrible..
This isn't true.. I'll admit they are very gear dependent below level 40 and do require frequent resting at lower levels as well.. but after you get to level 50-60 they are awesome and can handle multiple mobs very easily.. I've seen my priest take on 2+ in AV and come out on top
That being said I'm in no way saying they are the fastest.. but still very fun and no where near terrible.
