Q with no CD is pointless and it just reduces enemy counter-play by giving Morde no downtime windows for them to trade with him and Morde already has extremely good wave clear.

Morde doesn't really need build-in slows - you can buy if you need the CC. The ult change is overkill not only you get double DFG's damage increase and 40% ms steal but now QSS can't counter it.

I'm a Morde player too and wouldn't mind him getting buffed but your changes are just too much and changing the cost to %hp doesn't make this version less OP.
