Now that you mention it the clarity thing would really allow two enhanced skills. I think I've found a temporary solution that might resolve the problem.

To further discourage the usage of level E for escape I think I'd have the slow on constant 50% and the self reduction scale on miss increase through skill level. Kinda like you are slowed by 50/45/40/35/30% if you do not hit a target and perhaps lower the dash range to 400. Shield is also only available on the enhanced version and there is no more cooldown refresh on it.

A nerf on W's penetrations could also be placed. The highest flat armor penetration I have ever done on any champion is with Olaf at 70 or so armor penetration with Ghost blade, full armor penetration reds and quints plus the armor penetration from ragnarok. I'd tweak it a few more keeping what you have mentioned in mind.
