I'll just try fewer hits. The one in SSE, for example ,has 1 hit.
since now Down B and N-B in the air only work once in the air they are more balanced but even then i think Down B should take much more time to actually fire since making small jumps on the floor still makes OP also since N-B in the air can only be used once it should really have more range now since this move has a preety good startup lag to compensate while down B doesnt.
also dont forget to balance a few moves like:
AAA combo need to put some knock back so ppl dont get stuck without a change to escape
N-B on the ground same as abode.
Side B on the ground it really needs to decrease knockback it can ko peach at like 60 and few damage its a boomerang not suposed to be that strong
N-air if you catch the oponent in the middle it does like 80+ damage i mean i did 84 one time thats too much damage not even FS do so much damage.
FS that kills everyone in the stage is kinda cheap maybe making it do a good damage and knockback but only kill like 60%+ ppl to be fair to the oponents or limit its range
Foward trow looks amazing but has too much end lag maybe addind a framespeed modifiar after he drops the oponent so the animation can be speeded up abit can solve this
