Arma doesn't have time to cancel his null in a teamfight, he bought that against succu ult obv, only succu could do that since he is jumping on succu. Does that makes sense to you?
Null is for succu ult because he can use it even when shrunken is on. But it's still bad... Enemy team can't do dmg to him while he is in shrunken anyways so going for heart or lifesteal is much better.
Nullstone against armadon KKKKKKKKKKKKK
