I've talkled about this a lot with other players in post game lobbies and come to conclude that
-His ult is fine, its the base abilities even when not in the 1on1 that are his biggest issues.
Passive's unending infinite trade damage even more obnoxious than
max rank W, except morde gets it at level 1.
Q's base damage meaning he doesn't even need the single target bonus to harass the entire cast out of lane
W's cooldown in combination with stacking up even when on cooldown.
E width for its length
He needs a
treatment with nerfs to every ability then some of that power introduced back in only afterward.
Lower passive damage by around 5% of its current amount, make extending its duration require three new attacks
Change Q single-target damage to 120/140/160/180/200% from 120/125/130/135/140%, remove level scaling damage, make the base damage a flat 70/100/130/160/190 from ~81-294 based on level and rank, lower Q scaling to 40% from 60% AP
W passive resource generation only happens when W is off cooldown
E width changed to ~
ice cream cone's max width
Let him keep his removing carries from team fights niche as is for the time being.
