You still beat him midscreen and can keep him from kloning, you get a plus way off the ground for free in the corner, stamina changes helped Kenshi in this MU as well.
Midscreen is the same, except jump distance.
Stamina changes didn't affect that much matchups like sub, rep or cyber sub where a slide goes under whiffed teleflurry and keeps the slider safe, plus or even allows a full punish depending on when it's done. Sub never got problems to get in vs Kenshi besides impatience from Sub player.
Expush was -1 before, it was safe anyway. Corner time is worse now, since jump option from sub became more threatening since the mentioned loss of exkarma. Risk reward favors sub in the corner now every time.
Sub matchup (Tanya and Kung Lao too, for example), is one of those matchups where exrk loss is vital.
And don't tell me to antiair Sub jp1 crossup with standing 1, please xD
