Most of that is a big NO.
The sweeps getting buffed is a good idea though. One I’ve thought about before. They are hard to buff though because the most common answer to blocked sweep, is to sweep back. So if something like player 1 likes to fish with sweeps sometimes, the worst that happens is usually he gets swept back and the neutral kinda resets. But if sweeps are made better on hit like making them not have backrise (like a throw) well now sweep fishing is much more risky because getting counter swept is a real threat.
Longer tech windows is just no. It’s already a frame bigger than sf4 (3+7 versus sf5 5+6) and that shit was too long as well.
In order to get thrown you have to have fucked up somewhere. You let your opponent dash in, or you didn’t AA, or you got knocked down… etc. a bunch of “yo fault” type stuff, games need to hold hands less and allow people to deal with the shitty situations they put themselves in, unless totally detrimental to the game.
Throws have no range, have low damage, have low to no further mixup ability outside the corner, and startup in 5 frames now which is 2 more than sf4 and 5 more than ST.
