A lot of people tend to assume that if someone has a negative k/d, they are a detriment to the team, and I just don't think that's true at all
I will use myself as an example. I'm plat 2 currently (not the best ik but I was silver 2 seasons ago so I'll take it), and I tend to play smokes most often. My k/d for the act is 0.98, but despite that I still have a 57.6% winrate because I can set up my teammates well.
Even on the agent I tend to play the worst on (Jett), I have a 0.88 k/d, but a 62.5% winrate, as I am constantly looking for entries and getting info.
Just because someone is bottom of the scoreboard, doesn't mean that they are the worst player on the team. A lot of impact can be had by having good vibes, comms, and knowing how to play your role.
