Kinda agree here a bit about the power surge. But would like to chime in my own opinions here as well
Feint: even more useless than some posts above me mention as Shadow Flare does what feint does, and does it better. The skill really needs to be re-worked. This isn't an idea thread, so I'll leave it at that.
Power Surge: Because of the potency of jumps, this needs to be looked at. Currently it serves no purpose other than to stack with Jump. If perhaps it affected Dragonfire Dive then maybe it'll be worth keeping around. We will have to see what new skills Heavensward brings for me to agree to totally remove this skill.
Piercing Talon: The skill at the present is ok at best. Would like to see its tp cost slightly reduced, the potency reduced, and a 9s dot attached. This would make it more viable as a once-every-so-often ranged filler.
Other than that (and the proposed mDEF changes ofc), I think the DRG skills are OK. The 2 AOE skills each have there place and uses, so there fine. skillspeed needs to be looked at, but thats coming 3.0 anyways.
