I tried to play a melee class after getting my summoner job to level 50 but it just didn't work out like I had hoped it would. I do agree that melee classes are indeed more challenging and you do get penalized more often with being able to only do low damage as compared to a ranged DPS. I don't however think that any of the range DPS need to be nerfed. In any FF game I always favored playing a ranged DPS and I always thought that ranged DPS classes are great and to me they still are because they are more functional. Especially, SMN, BLM, BRD because we do tons of damage and sit comfortably in the backrows. I sincerely hope that SE will fix the melee class damage because I want to try out another melee class but not at the cost of suffering constant damage penalties.
