I agree not having any counterplay is a bit too much, and while removing it when he dies means he can just cast it and then run away, it has very low cast range. And even if he did manage to run away he wouldn't be able to participate in any team fights without risking death and thus the mark disappears, while the marked champion can fight freely as he will die unless Zenbakia is caught.
