I have been trying to figure out what is better a mage or a warlock and i cant seem to decide? Please if u can tell me which one is better at these things..... EOA, pvp and dungens.

Mages are more popular than warlocks in WoW, I think Mages are better in PvE and are funner to play because their spells look cool and can teleport/make food etc which helps out alot; they are also one of the top contributors to damage. However typically warlocks are better in PvP and is fun to play with them there because of the mind control and minions etc, so it depends what you enjoy more.

Warlocks are still good at pve though and mages are good at pvp too

But overall, Mage > Warlock

Mage is better at EOA but locks are better in dung.

I play a mage and normally top on the DPS charts. They are very good for DPS, crowd control, and PVP. I use arcane for raids, and frost for PVP which owns. Additionally people love mana biscuits!

Yes i have played mage many of times and it is so much fun and better than a warlock also because they have all sorts of different kinds of spells. all tho warlocks can have minions like pets that attack other things and they have spells of its own and warlocks are a little easy er to level up on and kill stuff because of the minions the y can have.
