You should also take into consideration their usefulness to a group dynamic over just shear damage output. Monks, bring little, but have big numbers when it can be sustained. Dragoons, slightly less numbers, but bring a very valuable piercing debuff that helps other DRG, bards, and machinists. Ninjas are the most helpful to a group. They bring a slashing debuff, a skill that increases all damage by 10% on a target For 10 seconds, goad, and threat management.
