I would love if they had Kara mechanic from SF4
I think they should copy a few aspects from RPGs
They already are with the likes of Quan and Kotal
But with the stamina bar I think they should play around with it.
Like have certain MB specials drain or freeze their stamina bar for a certain time period so you can rush down oki the opponent for free without worrying about op back dashing, maybe even have moves that freezes ops Meter so they can't use or gain any Meter for a certain time period .
The possibitus are endless, they have DOT so they could have MDOT (Meter Drain Over Time) like let's say Reptiles MB spit for example could slowly drain Ops Meter when in the range.
I was thinking for a Kabal variation they could give him a buff move that gives infinite stamina for a time period and MB version can give him also a buff in chip dmg.
I love how outside the box NRS are with this game you can feel the motivation and excitement from the devs when you see these gameplay vids
