"Half our students are below average!" kinda vibes - KDR necessarily means that for every person with 1.5, there is someone with a 0.67, that's just how the math works. If I'm anywhere near 1.0, I'm happy.
That's why recent games moved to counting eliminations instead of kills. If you contribute to the kill even if you didn't land the killing blow it'll count as an elimination.
Remember, KDR is a flawed mechanic. I'd trade a 20-2 player who farms eco rounds for a 10-12 player who gets those essential kills that win the round/match/etc.
