Vanco with Edward as a close second.
I remember when I went 2v1 v Cyren and Edward. I was able to keep Cyren regular mezzed for 3 + minutes while mavstab logged out of his group, crashed, switched to Mavleach, ran all the way from KC to rotting skeleton and then killed Cyren.
While all of this was happening Edward was chasing me and didn't land one hit.

Best part is, he then gate potted which is hilarious because noone's ever reacted to Edward getting YT'd. Maybe a slight chuckle?
