Ninjutsu - INT based damage
Blades - STR based damage

Allow individuals ninjas to scale one way or the other, and make both viable, whether it be a Magic Heavy ninja or a Melee Heavy one.

Doubt much it'd ever happen, but would certainly add some variability in the game.

in DCUO, Jobs had Precision and Might as stats, Precision affecting weapon damage out, and Might affecting damage done by powers. So depending on your focus, you could get alot of variation.

For that matter, what if they brought out Corsair with a Melee Weapon AND a Ranged Weapon, and gave motivation for using both or focusing on one v. other. DEX & STR.
