Id like to think as a joker player I want them to back dash. Closer to the corner the closer I am to 100% combos
This is true, but the problem is when people have enough experience with Joker midscreen, there are options that many characters have to push forward past the teeth rather than retreat further into the corner. The only teeth trap that is universally safe and guarantees at least a guessing game is 212 xx teeth, but that doesn't work universally because a significant portion of the cast has a mid whiffing issue with the final hit of this string that gives them a free combo punish. This, and LBSH, some improvements to the trait, are the only things we really wanted them to fix with him before the end of patch season, and it didn't get any love because Boon listens to asshats like JRosa saying all he needs is his parry to have 1f startup... sigh.... we tried so hard to detail what he needed

.
That said, the character still has his dirt and is alot stronger than most people think. While he struggles midscreen in some matchups and has a tough time getting through good zoning, his corner pressure and combo potential is absolutely absurd. It makes him hard to classify in the "tier" spectrum, but who gives a shit about that anyway. He has to tools to win in any matchup in the game if played properly, you simply need to know the matchups very thoroughly to pull it off in some cases. If the supposed worst character in the game (not the case) can say that, I think things are looking pretty good overall.
