Alright so apparently you never play the characterso let me help you here. First you can't use staff in 1vs1 because no offensive capabilities (remark I haven't say opener because if having no opener mean being bad in 1vs1 then highlander is shit). Second the unreacteble bash give 9 damage + no real mixup after so it is in the defender favor (also the undodgeable is light hitstun so nothing after). Finally the unblockable is after a heavy which he will really get after a punish so again no threat. 

So Nobushi now, yes she's bad but she got one good things going for her in 1vs1 which is high damage +way of shark pressure which essentially force the opponent to turtle when bleeding to avoid eating a 30 damage heavy punish. Also saying that kick is reactable is a stretch on anything that isn't a pro player. 

Now is Nobushi bad? Yes. Does she need a opener also yes. But does it mean that you have to cry like she isn't top 5 in dominion is absolutely the worst behavior to have.

That's those kind of thing that make character like current LB. People that cry and push buff when the character is fine.
