Make Morde Passive Reset When Hit by Hard CC?

It seems pretty clear, to me at least, that new Morde is pretty overbearing. Maybe he's not super busted but he feels like an uphill battle to play against almost all the time. But instead of another rant about all of Riot's terrible gameplay decisions and whatnot I just have a suggestion. Why not make Morde passive stop when he's hit by hard cc, kinda like Aurelion Sol passive? Its already terrible to be a melee champ and constantly have to fight Morde in a cloud of max health per second damage, but this gives that feeling a bit more counterplay. You go in for a trade, you both hit each other 3 times and as Morde passive starts you hit your cc, resetting his passive and forcing him to hit you 3 times again if he wants it back, giving you time to continue fighting or back off. This also doesn't just wreck the Morde, dodge the CC and then you get to wail on the enemy laner like normal. This way you also don't have to just nerf his passive damage into the ground or remove the movespeed from it, both of which would suck.

Aside from that idea I'd like to hear any thought you have about New Morde.
