I don’t play Dragoon much, but isn’t Stardiver AoE, ranges, and off the GCD? How in the world can you compare that to your third melee combo, which is ST, melee range, and on the GCD?

I can see what you’re asking for, and I agree I find Dragoon a little boring. But that’s the gameplay — you do damage spread out over all your GCD and oGCDs, the latter of which you have MANY. It’s a busy job with a straight forward rotation. You play the class if you like weaving.
