Sorry to burst your bubble but Lvl 50s wearing Morale gear are not anywhere close to being strong in 30s or 40s bracket. Strongest 30s will be people who attain a full set of multi stat gear off Haukke Manor whereas 40s will be people decked in Stone Vigil + Dzemael gear (Gear must be equip requirement under or same with the Sync level but Higher iLvl).

Dragoons are the strongest at 40s bracket, while WHM are the stronger healer in that bracket. Can't comment much on 30s bracket since I only touched once or twice. Just for your reference, my BLM 2.5s cast at 50s bracket is 2.19s with food, at 40s bracket it is 2.48s,
