People need to remember one thing, MK9 was a game that it was and some characters were strong in that game not only because of their tools but the way the game was designed.
Jailing people in crouch or stand in that game was a thing, some may thing like irrelevant, but characters like Kabal and Skarlet were probably among the first 3 who could effectively use this mechanic to make their game even stronger, Kabal with 2NDC and Skarlet with her blockstring being.
The chip damage in MK9 was 2% of health and 1% at the very least, you could have characters doing 50% of chip damage for that matter.
Wakeup system had 11f of invincibility meterless, and 21 with meter, something MKXL didn't had, the Jump arcs were also all the same height and speed and all attacks were generics and equal which made easier to anti-air in general.
MK9 characters can pick up other characters out of floor post knockdown
MK9 Character armor is not ruled by how many hits it can eat, rather than this, its ruled by how many frames the armor exists on some attack, MK9 characters could sustain more than 2 this of armor on their daily basis, a concept which was given to jason later on with lots of reppercussions, remember Skarlet and her super armor?
There is no way you can compare any MKX IGAU or I2 character to what kabal is or was or what the other characters are, they all will behave weird because each one of those characters in their games they're bound by some rules which doesn't apply in some other game
