Seems to me you just wanted the class to be something its not. If you had any real experience with Red Mage in past final fantasies you'd know its mostly a caster class with melee as a type of little bonus (as it is in FFXIV). Hell, in some final fantasies they primarily used staffs rather than traditional melee weapons.

As far as the rotation being boring is concerned, I actually find it more fun than than my other DPS: Monk. As well as the other DPS I've tried here and there in PotD. Other DPS tend to be about buff management and/or positionals, which I simply dont find fun, I find it tedious. Not saying RDM isn't simple, it is. But its, imo, a fun thing to play.

I mained tank since ARR, now I'm maining RDM, and I can definitely, without a doubt, say that RDM is more complicated than playing any of the tanks.
