Vayne Fix
I think the champion, monster or minion vayne condemns should briefly knock up and do the damage to the units it moves through like a lee sin kick but without the maxx health damage because vayne is supposed to be kitey but the cc is single target and that isnt the best. In the same vein, I think that she should get the yasuo Q treatment and abilities go up faster with attack speed not cooldown reduction, like the diablo 2 trapsin
