Lower lifesteal
I'm sick of yasuo and some adcs being unkillable after getting bloodthirster, as an assassin you can't even do your job while you get critted to death and kited by a lucian you can't even catch.
Oh, you finally caught him? Unless you're rengar you won't even be able to burst him because you do your combo just to realise he got his full health back up and your screen is gray for the next 60 seconds.
"You have ignite/executioner's calling" Ignite is up only once 300 seconds or so, and executioner's calling is totally useless if you're a mage/AP assassin
Call me salty and downvote me, but I had to get this off my chest. Go full damage (or full tank why not, tanks deal the most dmg anyways, who cares if you're the adc), grab a bloodthirster and grab your win
