Yeah I just have a problem with the first and final boss where they both can stun lock you till you eventually die.
Like you said if he gets you in a corner don't expect him not to use his tazer over and over faster than you can even jump or run or attack.
For the last boss he uses the self promotion over and over and over now normally your able to escape it. That is if you are close to the area that he cant reach. but if your even a inch to close then he will spam it until you die. the only way you can escape it is if you have a tazer of hadoken ready but unless your playing conservative I doubt you'll have em for the entire fight.
