More player input would be great all around. But I'm already noticing a pretty key issue with Street Fighter/bigger fighting games and changes - the bigger the pool, the more opinions on how things should work, and the murkier the waters.
I don't mean to throw shade at people, but some want the DP change back. Alright, so what happens to the characters that benefit from that? How are you going to make them viable, since the DP change is giving a bunch of characters life? You'll get a hundred different opinions depending on who plays what and what skill ranking they are in.
And the time period of when you ask matters too. James Chen tweeted out about mashing lights on wakeup, but he had no idea the player wasn't simply mashing it for no reason, it was because the character matchup called for that. It wasn't until he did research that he saw the reasoning behind it.
David was talking about Ryu like the character wasn't a problem even towards the end of S1's life. But Ryu was doing big boy damage without much meter and everyone from pros to casuals dreaded getting hit by the truck that is that shoto. I'm not saying the nerfs are completely fair - that motherfucker needs some reach and a better fireball to compensate - but people are real quick to forget things in terms of how games were even a few months after changes hit.
This isn't exclusive to fighting games. It's probably more prevalent with SFV because there are less changes than with SF4, There are things a beta could catch, like how many, many players did not like the input lag and still don't, and I think them gleaming more input would have maybe dealt with that far sooner than not. But at some level, the game just needs to be made and people just need to adapt. This isn't really what you were implying, but I'm more so just hoping Capcom doesn't completely flood their game with community input, because the majority of it isn't good and rarely ever agreed upon with the scope of how many people play SF.
tl;dr: I hope Capcom takes community input into consideration on bigger issues, but the community and Capcom need to just let some shit rock and have better communication so that things like the DP change aren't complete surprises.
