Dragoon:
I really like most everything about Dragoon except one thing - jumps. For being so iconic, I don't like the way they work. My knee-jerk quick and dirty change. All jumps are ground-targeted AoEs. (Don't need a target to jump now.) Potency would have to be reduced accordingly, however. The other change I would make is that while in a jump animation, Dragoons cannot be hit by targeted AoEs. (Cones, circles, etc.) Arena-wide AoE's still would. Not sure how that would affect stack mechanics, however. Like I said. Knee-jerk.
