Yea once you get to 50+ dungeons you are not going to pull more than 2 small packs with just mages and it will always be risky, trash mobs up to scarlet monastery hit for nothing, once you get to ZF having a warrior starts to pay off.

Keep in mind that mages use a lot of mana for aoe’ing and you will be drinking constantly, so if you can bandage+ loot the mobs while other chars are drinking you will save a lot of time and greatly improve your exp/h
