An anti stealth character should be introduced

A character who's unique ability is that he can target a stealthed enemy,
or
a character's special move that deals bonus damage if the target is in stealth (and obviously can target the stealth enemy)
or
a leader ability that allows your team to target stealth allies with an extra chance to miss, but if hit removes the stealth and grants offense up to the attacking character

now that we have stealth becoming more common, why not? (not a far off shot from Grievous having 100% hit chance, right?)
