check out https://www.vlr.gg/160667/vlr-gg-player-rating-explained
but yea, as mentioned above, in general the rating favors low deaths
its why leo has SUCH insane ratings despite a lot of his value being impossible to track with numbers - his playstyle fits perfectly into how the rating system works
Its great for comparing support players statistically, but I do find ACS being a better number for duelists since (as an example) even if they get traded, getting a kill during an entry is good value (which the rating system would then devalue compared to the support players cleaning up the second person on site and not getting traded)
