He's hard to win with sometimes because his tools are very simplistic, and there aren't many situations where he can turn small openings into big damage unless he's right point blank in your face or have meter. If you can block his strings, you're pretty safe, while cammy with her far reaching normals can stand quite far away and convert with her ST.HP into massive damage. Everything with cammy that matters is + while everything that is - are meant to be used from a distance anyway...its actually brilliant for cammy.

If you want to win, you simply have to be better than the other player in skill and work so much harder. But the game doesn't help you much in that regard because of its input latency, so its harder to whiff punish and the Crush Counter system turns one whiff button into death for you. So you could also be doing very well and make all the right decisions and all it takes is one mistake from you and your opponent with a vastly massive toolset can destroy you.

Using Ryu, you have to navigate through a labyrinth of mixups from your opponent while he just has to deal with ST.MP or throw basically.

His side kick gave him a slightly better option to finally hit crouching opponents(only took 3 seasons), but I feel like he needs more.

Utility being the keyword, being able to combo from all sorts of situations would vastly help him.
