lao's low hat was -7 which made it better for pokes. His ridiculous damage was also ridiculous, 60% corner combos. He'd be tied for number 1 with kabal most likely.
Sonya had an inescapable infinite with d4 ms (maybe escapable with breaker). D4 does hardly any chip but she could always mix in throws and you could just time out. if this weren't banned in a game, it'd be pretty ridiculous. She still had armor on ex cartwheel but not on all frames.
JC had a sweep that's +11 on block and he could OTG reset with d3. In the corner, he could combo off sweep into nut punch, difficult but possible.
Cyrax would have maybe 1 bad MU in kabal. He had an actual infinite that was only escapable with breaker. command grab reset that was hard to tech was OP. There were also the buzzsaw resets but they're not much different from the double net resets.
Raiden had a better teleport and a better superman. Taking risks with raiden back then wasn't as bad as it is now. Ex tele was worse though.
No dlc would make the tier list look different. Kano would still be garbage.
