For me it feels more like this with no paricular order in the tiers:
S Tier:
Tanya (most favorable match ups)
Kung Lao (no losing match ups, best anti air, best jump attacks, etc.)
A+ Tier:
Raiden (best corner carry, best corner vortex, safe 50/50s, etc.)
D'Vorah (top footsies, no hurtbox on stingers, etc.)
Quan Chi (best mix ups, best come back factor)
Kenshi (unbreakable damage, meter gain, favorable match ups, etc.)
Cassie Cage (best punisher, top footsies, etc.)
Shinnok
Jax
Erron Black
A Tier:
Sonya Blade
Kung Jin
Ermac
A- Tier:
Sub-Zero
Scorpion
Kano
Johnny Cage
Liu Kang
Mileena
Kitana
B+ tier:
Reptile
Ferra/Torr
Jason
Kotal Kahn
Jacqui
Takeda
Goro
Feels like every character is close to each other at his tier! even tiers are close to each other!
For example for me jax and goro are higher! because noone uses proper goro doesnt mean he isnt good..
