Idk like nobody uses sweeps at all during neutral. So maybe getting a hard knockdown on counter hit could provide more uses. Its like one of the most least used move across the cast
A large part of that is that it's a heavy.
How many characters really use sHK in Neutral? Valentine (and Fukua if you count whiffcancels).
sHP and cHP have a bit more widespread use, but still aren't really buttons that most of the cast presses a lot during the neutral game.
Sweeps are Armorbreakers (useful!) which present you with a low option at a distance / point in a chain where one otherwise wouldn't have one, eg:
- BB sweeps at midrange, where his opponents just standblock to avoid both Atrain and GStep
- Parasoul can cLK cMK cHK to hit people who hold back/upback after the cMK to avoid the 4HK overhead
- Bella cHK will become more useful now that 6HP can be upbacked to avoid people just jumping away from MGR at midrange
Sure, none of these lead to ton of damage, but that's why Sweeps deal 1200+; people can't just go and keep eating those over and over either.
Aside from that, Sweeps often times have a bonus component that makes them useful even if you don't plan to hit with them
- Peacock Sweep is crucial now as a mobility option
- Eliza uses Sweep xx DP to get through projectile hell
- Filia/Fukua can use cHK whiffcancels to get into position for things (xx Updo / xx Dart)
- Parasoul can cHK as the best antiair in the game (#1 tech!!)
I really don't feel they're half as weak as you think they are
