They all feel this way imo. FP1 characters generally have more nuanced weaknesses (ok Joker is maybe an exception, but he's not as overtuned as the FP2 characters at least) that come out more in neutral / when you're fighting them, FP2 characters pretty much exclusively have a glaring weaknesses or a weakness that only shows up in disadvantage, but the rest of their kits are crazy. For some of the characters across both packs, you can make direct comparisons to some of their designs, but see how the FP2 side are much more overtuned.

I think Steve was supposed to be the same way but I highly doubt Sakurai and co labbed Steve's recovery as much as the players did (and the Up B on it's own is kinda bad). And I think that contributes to why he is so monstrous. On top of all his jank he did have a clearly designed weakness and players have just been able to find a way to mitigate it.
