It’s hard to give him any significant buffs because, IMHO, if the did anything like increase his damage or give him an above average wake-tool, he goes from being low tier to almost breaking the game. As a new 'Sim player, I wouldn’t oppose, but I also wouldn’t want to be using an S character like that. That’s part of the reason I like 'Sim in the first place.
But regardless, he should be given some more tools to make him a little more viable. He’s got too many bad matchups, and that’s not gonna get fixed unless we get make a stink about it to Capcom. If there’s anything that could get results I think we should at least try it.
Actually, it would be pretty cool if they brought back some of his SF2 tech, i.e. The 48 Killing Arts of Yoga. Would be a nice homage to the past and the fans as well as make him more viable without making him too godlike.
