I've just found a way to calculate your real win loss ratio.
Since they added medals into combat record, it shows that i have 639 victor medals and 285 strength and honor medals. If you add them up, that's 924 career games played total and 639 victories, which equals a 69 win percent, which is about a 2.20 ratio, yet in game it shows me at 1.19.
That's because this medal way doesn't count your joining in the middle games and it doesn't count host rage quits that suddenly end the game.
It's pretty much your real win loss ratio, because when the host ends a game, you don't get a strength and honor medal, so it doesn't count against you.
It's absolutely insane how much host disconnects and joining in the middle destroys your win loss ratio. That's exactly why it's an irrelevant statistic and objective play on leaderboards means more; however, now you can see a person's real win loss ratio before you judge them on their shitty one.
