I did see a DH get soloed at the start of the round in a shadowy duel I’m almost certain it was after the nurf. Maybe I’m mistaken…
He did complain about “Not getting a heal” 
So likely didn’t use anything just got 100-0. It was a free win for me so I was ok with it that time :P.
C’mon now…
I have to trinket/blind or bubble to not die in a kidney smoke bomb, when sub has blades and shadow dance trinket. A sub can still 100-0 you in a KS. Maybe it’s just luck but videos out there showing players getting killed or nearly killed inside CS.
