If not looking toward number, your idea of skill is pretty good.

% armor/mr reduction aura is too op even without double / triple.

The idea of getting movement speed when enemy is not facing is good, it should give very high movement speed bonus and goes higher with each level.

He should has other way of invisibility though, if his ult can make him go invisibility for few seconds it would be perfect.
