Red Mage is OP when you first get the class I think

Your stats vary with gear (and to a tiny degree, race). If you have a RDM and SMN at 50, same race, gender, clan, no gear, same weapon family (ex, both wearing Ironworks weapons) no food buffs, they will have the exact same HP and INT values. RDM is overtuned for old content because they have Deathflare on a 30 second off-global CD super early on. :P They also have most of their potent spells already, while SMN has to wait until later levels to get fun stuff like Deathflare, Bahamut-egi, max upgraded DoTs, etc. RDM gets upgraded with levels too but the nature of how it plays means that it just machine guns high-potency spells from the start while SMN needs to ramp up a little longer.
