Which is the best duo for say 50+

[Esper]

I've duo'd with every class and i'm a 50+ cleric, i've found actually the fast to be duo'ing with fighters.

The thing is though they must be 2h axe with lic and be willing to spam skills, I used to duo with my axe guild mates all the time (before patch) and I'm pretty sure some of them can kill orcs faster then a mage or archer.

also, with a fighter duo you can mob lots and aoe them with devastate.
