Gladiator

Gladiator has the third highest single target damage in the game, with a skill ceiling between that of reaper and spectre, and can deal nearly as much aoe damage as wizards, if utilizing the oc + sc swap for whirlwind.

On top of their damage, the 145 helmet gives enemies a 15% defense debuff, allowing spectres and reapers, the hardest hitters, to do even more damage.
