Idea for Nasus Q

I have an idea for Q. If Q was a bit like stacking it would add a nice counterplay. How many time have you heard "Just don't let him stack."? It's not always easy to not let farm, because even if you are able to deny him from a minion he can just get one next to it. A bit like there could be a mark only on some of the minions (chosen randomly) spawning and same for the jungle monsters. would need to last hit minions or monsters with the mark to gain stacks. Because of that, could have a buff on an other part of his kit and then there would be a really nice and fun counterplay to his stacking. There could be another option, instead of buffing another part of his kit, the marked minions could give more stacks. This would give a higher skill cap: better players would be more rewarded and worse players would be more punished.

I think this would add more counterplay to while rewarding players who are able to kill the marked minions and punishing those who cannot.
