Disclaimer: I'm very new to the game.

I'm a level 11 warrior (level 5 cleric, haven't put much effort into it). I'm trying to figure out where I'm going with this.

What adventurer class deals the most single-target melee damage? I like being able to tank a bit also, and with my wife going the Mage route, I have a feeling I'll need to be able to soak a fair bit of damage when we're leveling together.
