So if RDM becomes the strongest caster and has good utility, tell me, why bring anything else? The very fact that the job is Red Mage means that it will have healing and raising as well as offensive magic. It is the hallmark of RDM since the very first game in the series. I'm really quite surprised that you or anyone would seriously believe that it should be stronger in damage than explosions and summoning bahamut.

It sounds to me like if you don't want to play that job then don't play it. Simple.
