You're speaking from the view point of someone who doesn't know how to properly use Stryker. I don't just throw random ass bombs and shoot at any time.
The bomb is an EXCELLENT anti-air that they buffed to make it even faster so I can handle the queers that spam jump kick or keep going for jump in combos.
The gun shot has the dash cancel so if I see the enemy react I can cancel into a dash block. And guess what comes after that? Punish. I don't shoot right away unless it's part of a combo.
The IAs and IAf isn't going to hurt me though. It's a roll and I am 95% sure it's going to go under the fans and sais. I dunno. You may be right.
And no, Sub-Zero's ice ball animation is longer than Stryker's quick ass roll so I always get them.
