Idea for aghs on Arc Warden, what do you think?

Arc Warden - Clone is identical to real hero from enemy perspective. Add sub ability, swap places with clone. *Maybe a small duration buff, 5-10sec)

I like this because it brings new gameplay challenges without adding any direct buff. But keeping in line with Zet, as a hero, has very interesting high skill implications.

In case anyone is thinking "too similar to spectre", I dont think its comparable, the point of this upgrade would be to confuse enemies and be able to use the clone as an escape that Zet lacks. Also, obviously it doesnt allow global movement.
