Currently kensei doesn't have a reliable way of dealing damage to your opponent his top light is fast but u can counter that by having your guard up top all the time. His side light and heavy are super slow and can be easily parried and his so as his side step attack. Furthermore even if you manage to hit your opponent with a side dash light punish or the top light, your next attack is so slow whether it will be heavy or light that people can block or parry it 9 times out of 10, so you will never get to use that unblockable ender mix up until you get a guard break or you whiff attacks toward your opponent but then he can just back off and let you burn your stamina. This causes kensei to play extremely defensively so that can get the parry guard break, this proves troublesome though as nobushi and lawbringer can not be guard break after parry, so all kensei get is the top light. What I suggest would be to allow kensei to be able start his chain with his zone attack which means that he can go in to the unblock able top ender right after the zone since the zone consist of 2 attacks. Currently his zone is almost useless, the only way people use it right now is by canceling the second hit of it in to a top light, but this only works once because after any one see this instead of trying to parry the second hit of the zone they just guard up and prepare to block your zone second hit or what ever u cancel in to. If kensei can chain the zone into a top finisher then your opponent have a better incentive to parry because they dont want to deal with the unblockable ender mix up. Also maybe make his attacks alittle bit faster so people wont parry ur side light 24 7, or so that he can get a top heavy off after a guard break so he can punish nobushi and law harder. As if right now I am happy that u consider buffing this character, these are just suggestion on how you should change him so that he is more usable at a higher level based on my experience as a prestige 5 kensei who does alot of duels.
