yeah i think what she needs is, her B12 to be -5 on block, and her B12 to have 8 frames additional recovery, its near impossible to wiff punish that move, this would nerf her obsene pressure, but still leave her intact for Mileena players, example she would be able to still OS off it, and could use it as a Space control tool, but would not be able to abuse it the way she does. and she would still be TOP tier just not S. she would be closer to A+.
and possibly ad a larger Hurtbox to her roll, it seems since her Hitbox that hits you is so large and around her body during roll, even if you JIK on it it wins the trade, that is kind of dumb, but why we should not ruine it completely is because its a Great Anti Air tool, and the game needs to retain moves like this, Granted she also has B2/B1/U+3 to Anti Air but why ruin one of the best ones. but yeazh honestly as much as me and other hate her pressure and versatility she is the example of an Honest Top Stier character. and thats what all other characters should aspire to be. Minus the B12's over and over.
