I play Dante on point with Vergil on anchor. I have been doing the Yipes combo(?) where you jump up and mash H as you call Vergil with rapid slash and then you cancel into hammer. That part I have down but sometimes when I Shower xxx Stinger for the wall bounce, the dummy hops over the Stinger but sometimes it hits. Is there something I need to adjust, it just seems random to me.
The reason they flip out is because you scaled the hitstun too much. The further you are in a combo, the more likely they are to flip out Do the shower into stinger before the vergil extension. BAM problem solved.
