Akuma was nerfed almost as much as Sagat; only in Akumas case, they didn’t affect his ground game the way it did with Sagat. Akuma’s ground game is still pretty high tier; all the tools work the same, only there is a bit of a difference when HP SRK goes from 190/200 to 150/150, HP Shaku goes from 150/200 to 99/105, sweep goes from 110/200 to 90/100, Demon Flip throw lags harder and does less stun, cr.MP/MK go from 70 to 60, and air fireballs get 2 more frames of landing lag.
As far as nerfs go, he got hit mainly on damage and stun output; particularly his heaviest combos.
Far HK, cr.MP, LK Tatsu, LP Shoryu, FADC, HP Shaku was worth 417/640 in vanilla and now does 346/473.
The point is emphasized when thinking about that combo when done from a jump HK (one of the biggest combos he can do). In vanilla you get 468/770, and in super you get 408/629. Imagine you did that in a match and followed up with a cross tatsu to sweep (190/250 vanilla, 170/150 super) that the opponent fell for. In vanilla it totals 658/1020, meaning they’re stunned… and you can do a jump in follow-up without much scaling. That would bring you total damage near 950; you won the round, basicly.
Super tells a different story. The total damage and stun from hitting your largest combo and the successful follow-up would be 578/779.
As monstrous as vanilla Akuma sounded on paper, he was still quite far from an easy win character.
In vanilla he had a great ground game, could punish randomness with combos that hit like a wrecking ball, and had a vortex to top it off. Now he has the same ground game albeit a little softer this time, risk:reward took a shift away from him and you basicly have to be a vortex monster. Stunning the opponent went from a matter of landing a combo and following up with 1-3 more successful mixups, to needing 4-6. He still takes stun like a bitch, mind.
This replay is a really good demonstration IMO:

He has the tools to be a potential top tier, although succeeding with him now demands a very high level of precision from the player.
