my two cents
option 1. no recoil effect on akuma’s air fireball. you still take damage while walking forward and can still be comboed but you do have an opportunity to retaliate if you eat the fireball. it still should be able to knock down if you attempt to jump at him and get hit. this allows for the defensive purposes of the air fireball. he still will have his cheesy-ass offensive weapon but you no longer have to wake-up to the 50-50 chance of getting swept into hurricane-dp combo or raging demoned. eat the fireball and then spd or dp whatever.
option 2. forward and roundhouse hurricane kick knocks down. THEY DO NOT JUGGLE. it would take someone a lot of skill to hit with a jump-in short hurricane kick then hurricane kick-dp combo. i could live with that. this would also allow for only one hurricane kick hit if you block the air fireball and then get swept into the hurricane-dp combo if you didn’t want to eat a raging demon.
option 3. both of the aforementioned together.
option 4. choosing akuma gets you dan hibeki.
