I have one suggestion, one statement and one question about this ability.

Statement:
First, the new end cost is perfect I think.  Much better than getting up your jin for a crappy ability.

Suggestion:
Maybe using aspect could give you two buff icons, invis and levitate.  So you could disable one part if you wanted.

Question:
Is it just me, or does the defensive target invis that this skill gives 100% amazing (My buddy can walk passsed 50 6dots), but mobs 5 levels (and even sometimes much lower) see right though MY invis?

Well it gives the defensive target an awesome invis now.  But the invis it puts on you doesn't even work.  I don't understand
