It's too easy to get a stike-throw mixup

They...

• block a raw DR > button? Strike-throw mixup.
• block a jump? Strike-throw mixup.
• block a cMK > DR > jab? Strike-throw mixup.
• got knocked down > DR? Strike-throw mixup.
• are in the corner? Infinite strike-throw mixup.

Defense in this game feels so miserable, it's basically a casino game.
It might all be caused by DR and if that's so, there's basically no solution to it besides picking a different game or waiting for SF7.

Of course to avoid it you can counter or reversal instead of blocking but there's also counterplay to that counterplay, so that doesn't really "solve defese".
