Im unsure of what to make next I have a 85 Warrior Fury/Arms so I want to make a caster class now and im unsure which ones going to be the most fun to play please help P.s. Damage isnt a big deal since these 3 do great damage anyways...

I would recommend a Enhance. Shaman. Their dps cycle is short, simple, and sweet. But out of the three you want. I would pick a Mage. They conjure up food whenever and where ever and just overall easy to play. Warlocks have lots of dots and you need to be on your toes. I don't know about hunters. Never made one, never will.

Mage- in my experience of playing it till about lv 35 it is a very boring class. really all you do is spam about 1-2 button rotations and their is your rotation till 85. i am not even kidding. for pvp obviously your rotation will be different because of the situations your in but mages are pretty squishy and usually get ganked on by rogues and feral cats and you will die fast. also if you pvp learn to utilize their tactics. this is a challenging class to play well in pvp.

Warlock- i agree warlock is fun to play; BUT difficult to play well. it's hard in pve because of all your dots and multiple targets but trust me your group will love you. you can top dps charts as destruction spec as well it's a 1v1 spec so really not many dot's to keep track of on multiple targets. in pvp though basicly what you do as a destruction mage you will usually die fast since your casting is clow. as affliction you dot and run away and fear. and as a demonology you pretty much half and half dot and do burst dmg and run. you will die fast as well in pvp by feral cats and rogues usually.

Hunter- Cookie cutter class for pve and pvp. its really HARD not to play this class well. their rotation is easy, Pvp with this class is easy ( obviously you will get ganked but which class can witstand a fking gank? NONE they all die ), can top dps and kill charts in pvp even with quest gear. only thing you do is keep your pet alive. pvp theirs many tactics to use so your not as bored

right now im playing a lv 30 hunter he is at least 1 or 2 on bg charts in his quest gear.

i STRONGLY suggets whatever you make deck it out in heirlooms and enchants because now a days thats what noobs do. they don't even bother learning the mechanics of classes and how to dispell but really at lv 85 you will have to or you'll just get killed too easily. a hunter would be best in this situation with all heirlooms and enchants because as a hunter in shet gear i owned warlocks and mages in full heirloom gear 1 on 1. warlocks are more challenging then a mage in pvp to me.

Warlock is the only way to go
