My main is DRG, and I consider it the only DPS I have leveled right now. I also have both Healers and Tanks leveled and geared (yes, I know I have SMN leveled too, but I don't use it at all and have no intentions of using it unless I want to troll people...yeah, I'm that bad at it).

I am leveling BLM right now, and am thinking of actually using it. So far I'm having fun with it, and its not nearly as complicated as DRG, so I'll use it when I feel like being a lazy DPS (and I don't want to hear BLM saying its hard...just recall what your ideal rotation is and compare it to DRG...)

Level a melee. Yeah, you have to work for your DPS and endure the stigma being a melee brings, but I do recommend all ranged to be a melee so they know what its like at least. Besides, its a lot of fun and a lot more challenging.
