Hey buddy, I don't know if you know this but Epic has already been toying around with a system like this. In the competitive ranked solo game mode they gave more points for more kills. There's a reason for that.

You may not like it but getting kills is a showing of skill and should be rewarded over shitters who bush camp. I'm not saying that people who get under a certain amount of kills shouldn't be able to get a W, but a ranked Win system makes perfect sense.

Sit in a corner all game and kill the last guy who's weak? Congrats, here's a bronze win. You did it, you survived!

Kill half the lobby and win? Here's a gold Win. Congrats, you showed your superior skill in being able to kill enemies while winning at the same time!

Get over it, wins may all mean the same to you but nobody will find it impressive winning a game with 1 kill lmao
