Kinetic Assault > Mass Driver: detailed info does not include the initial smashing/energy damage.
Kinetic Assault > Impulse stacks do not give +recharge, at least according to the in game stat monitor.
Ninja Assault > Flashing Blade, Steel Wind, Scorpion Sting: This might a big ask, but I figured I would throw it out there. Another model or two for the knives would be nice. Pretty much have to pair the knives with the legacy katana for visual coherence between the melee and ranged powers.
Ninja Assault > DPA on attacks generally seems a little high.
