Oh yes the DPS won a 1v1 duel with a support.
You were the one that took the duel, with the understanding that he had both the means of closing the gap and securing the kill on a squishy mobile target. which you are playing.
You were out of position and got punished for it.
I’m sorry but you were the one that made the bad play.
I also like to point out you had the chance to punish his roll with your Large AOE effect boop.
