In the last warrior's den Roman (head game dev) said that while kick is powerful it's meant to be and is a core part of the shinobi kit. If they do decide it needs a nerf it'll be a ways down the road and they'll need to buff some other aspect to compensate.
So no, to me that says no nerfs anytime soon.
Just take away the kicks' super armor or make it at least TRADE with other unblockable/unparryable attacks like shoulder bashes. Right now the fact that your ONLY option vs a kick spamming shinobi is to dodge, no other possible counterplay, is annoying. and with Backflip, only a couple classes can even PUNISH a whiffed kick. It's annoying as hell.
I'm all for giving the class something in compensation. Just take away how kick is super safe with backflip and has virtually no counterplay.
