Action changes to:

[RdehlikaJenma]

While I can't comment on the other two, this one I'd personally hate. The way I have organised my hotbar has me strictly separate my abilities that involve movement from my abilities that don't, to ensure I don't fatfinger any of them by accident. As such, having High Jump turn into Mirage Dive would be extremely annoying.

(High) Jump doesn't involve movement at all. it puts you back at your starting point during the animation
