Ok, I feel like I'm missing something here. Is there a way to make your character drop down faster after an air spike to continue the combo? I feel like I'm coming down way too slowly to pick them up and launch them again. I'm trying Ultron's flight air fierce combos and after the HK I don't know what to do to make him get to the ground faster to follow it up.
Edit: Or maybe the last dash is a horizontal one, I don't know, but it feels like that's happening with several characters for me.
Slow down your air combo for most characters. For Ultron you can do his dive move after the FP loop in the air.
