I got that newborn thing going on, too. Sleeps on me every night.
Let's not pretend that the fans were directly responsible for any of the balancing in Street Fighter 4; the majority of suggestions were ignored, and it is a good thing they were. People ask for crazy things, claim things that are perfectly fine are "OP", claim that their incredibly strong characters are weak. It is endless. In fact, the only times I can remember Capcom directly reacting to fan outrage was with Marvel 3 were they hastily adjusted the game based on fan outrage, nerfing Sentinel (because he was "obviously OP") and Pheonix Write. Yes, based on fan outrage, they fucking nerfed Pheonix Write.
For the most part fans are extremely anxious, nervous, reactionary gamers howling about things that they don't, and quite frequently couldn't possibly, fully understand.
This is completely wrong. Fans weren't outraged about Wright at all. They were still debating whether he was even useful. ChrisG used him on a joke team even pre-nerf just to clown on people.
Sentinel was a scrub nerf due to Capcom scrubs. Seth Killian said as much. There was an internal debate about whether Sentinel is OP, because he bopped a lot of Capcom employees. Seth tried to keep him from getting nerfed, but to no avail.
If Capcom listened to fans, TACs would have been completely revamped. Zero wouldn't have gotten buffs. Tron and She-Hulk wouldn't have gotten nerfed.
Here are things Capcom HAS listened to fans about:
SFIV oki being too good, leading to delayed wakeup.
FADC out of DP being too good, leading to a frame data nerf.
Option selects lowering skill level; many are gone in SFV.
Back dashes being too good.
Ultras being too good for comebacks.
The vortex being bad for play.
This is all fan feedback that has led to an improved game. If you listen to every voice, it sounds like madness, but if you listen to what is being yelled from the rooftops, it is generally good feedback. Players might not know how to make a great game, but they know when they aren't having fun.
