How I would buff Zed
Q - Razor Shuriken: Units beyond the first take 60% damage >>> Units beyond the first take 75% damage. In teamfights when you ult a squishy target they will usually be surrounded by tanks which can body block Zed's Q and reduce both Q's damage and Death Mark's damage.
R - Death Mark Passive: Killing an enemy champion (whether is affected by death mark or not) restores 30/35/40 energy. This will allow Zed to stay relevant after he kills a target.
This is my personal opinion so feel free to disagree.
