I’d say just nerf Raikousen so it doesn’t cross in the corner and minimum scaling for 10% in specials and leave everything else alone.
Zero is much more fun to play in Ultimate because of buster cancels…
Don’t spoil that!
With minimum scaling of 10% the damage of a full scaled lightning loop would be 1/3 of what it’s today… so a perfect LL (hitting every hit of every lightning) would do about 140k damage (as it stands today, each lightning does 35k in 30% scaling if all 5 hits connect, a full LL is 12 lights… you do 6 commands and sougenmu does the other 6) + buster (about 30k in 30% scaling) and a extra lightning, in 10% scaling, fullscalled a dive (7k), buster (10,8k), light (12k) into a perfect LL (140k) with 2 extra busters (21,6k) and a extra lightning (12k) would do about 203k damage and that’s almost the same damage you’d net for one meter from Rekkoha (180k)!
the only advantage you’d have for executing this over rekkoha after this nerf would be the possibility of repeating it at the end… and still… you’d spend 3 meters, a lot of time and execution to do the same damage you would do with a single LL today…
it would be about 70, 80% more damage than you’d net with a single Genmu Zero at the end of a combo. And that, ONLY if you manage to actually make EVERY HIT from every raikousen to connect.
seems fair, IMO.
I don’t think removing the highest execution combos and options is the best way to change a character.
MAYBE you could extend the time to charge buster a bit OR give it a little bit more recovery to make it less stupid in neutral.
