I think multiple V triggers and Multiple supers are happening.
I'd much prefer if whatever new stuff they give the characters it was loaded onto their current toolset as opposed making multiple versions of everyone. People complain about some characters lacking options or some characters being forced down into a playstyle. More moves could rectify that.
I'll reiterate what I've said before because I'm at work for another 30 minutes:
1. Multiple CAs is an issue because current CAs do everything well. Easy as shit to combo into, high damage, and fully invincible describes like 90% of them. Ultras in SF4 worked well because some would act as anti-airs or throws which forced the opponent to play differently when you had Ultra.
The solution would be to tone down the current CAs and/or revamp the meter system to be different sizes/multi stock like 3S.
2. Multiple​ V-Triggers runs into the issue of not enough unique mechanics to spread around. By the end of S3 that would be 68 VTs that, by design, should feel very different from one another.
I'd prefer if VTs were just made better and do multiple things. Every VT would be a power up while also doing something unique by pressing HP+HK again like how Urien has to do to summon another Aegis. If a specific VT move is really strong doing it once burns through the meter.
