No health increase for Akuma. A health increase spells nerf to his moveset.
What Akuma needs to keep up is improvements to his already impressive moveset.
1 - Demonflip needs to be throw invincible on the first frame. I’m not looking for a speed increase, but just throw invincibility. This way Akuma could escape tick throw setups with demonflip, and it would make it risky to attempt obvious throws on Akuma but not actually increase the speed of the demonflip.
2 - EX fireball needs a speed increase on both execution and recovery. More along the lines of Ryu’s fireball. I say EX over normal fireball because Sagat and Ryu need to be superior to Akuma in some regard, so their normal fireballs should still be better for pressure. However Akuma needs to have a true block string with his fireballs, and using bar to achieve that I think is fair.
3 - His medium and large hurricane kick need to be improved in some capacity. Honestly hitting on the third frame like they always have in the past would be useful, but that may be too good. As they are right now pretty much useless beyond air applications.
4 - Second ultra needs to be KKZ, ala third strike. Massive chip and monster invincibility would be very useful to win matches. Akuma in other games was always a big chip damage threat, but with no super fireball that KKZ fits the bill.
