Answering to your questions:

The point of the ultimate was to kind of tease your opponent, throw a blade to stun and deal damage, remove the blade by pulling it from your enemy causing him to bleed, and then stab him with the same blade once again to finish him off, kind of like Cat playing with defenseless Mouse. And the dash is mostly to ensure the kill and clarify it a bit (after all, you don't backstab people's faces).

Yes, circle lasts 4 seconds (more if you continually attack this enemy), it would probably be more 'vayne silver bolts' way, just to make sure that buying one item won't make your mobillity skyrocket to the freaking Jupiter. I guess I'll need to write that down somewhere.

About the E, as an all-in spell it's really strong, since it has quite long range and gives attack speed, but then you sacrifice most of your safety, and using E to escape would in most situations be hard (that's the aspect where SIV HD would shine, because jukes), I'll try to look into it.
