Current survivor MMR system contributes heavily to the "giving up" epidemic, this needs to change

The current MMR system is unfair because it is based solely on someone escaping or dying and not any other factor. It doesn't even give people more MMR for escaping through hatch

DbD is asymetrical, so MMR should not be based on winning or losing. DbD can't be compared to a MOBA or hero shooter.

There is no clear win or lose condition. One side could partially win wether it be the killer only getting 1-2 kills or the survivors getting 2-3 escapes

If a survivor gives their life so the other three survivors can escape, then who won? The killer or survivors?

Also unlike MOBAs or hero shooters, there is no such thing as a permanent death. If you die, then you respawn. But in DBD, if you die thats it: you die and your out of the match. In the case of MOBAs or hero shooters, its often based off how well you are doing in regards to the objective and it encourages teammate. Doesn't matter if one team in Overwatch 2 got more kills, they didn't stop the payload from reaching the final location and as such failed.

But in DbD it doesnt work like that. The system encourages people to be selfish. Why rescue the other survivor when I could just leave through the exit gate? Why do generators when I could just sit in a corner or stealth around the edge of the map, knowing that the killer will patrol generators? Of course I don't do that but the game isn't exactly rewarding me for being a good teammate. Dying would feel less awful if I knew it wouldn't lead to me getting shittier teammates the next game.

So what is the solution?

Have TWO conditions contribute to MMR increase:

1. Wether you escape or die, like before

2. How many survivors managed to escape

With how MMR works right now, it encourages people to be selfish. The fact that someone with urban evasion + distortion crouching around the borders of the map can rank up but the player who gave their lives so the other three survivors can escape is forced to rank down? thats not fair

And bad teammates can lead to survivor deaths. So it's a vicious cycle of being trapped in lower ranks with bad teammates and dying because of it

But if the MMR system rewarded people for other survivors escaping, and not just them escaping, then this would encourage people to do things like generators or be altruistic without going back to the mess of the rainbow rank days.

Everyone escaping would be preferable and give the most rank up, but if I gave my life so the other three survivors could escape then at least I could still rank up partially. Giving my life so others can escape would get me 2 points (-1 point for dying, +3 points for others escaping. 3 - 1 = 2), whereas the immersed survivor crouching around the map with urban evasion + distortion would get - 2 points (+1 point for escaping, -3 points for letting teammates die. 1 - 3 = -2)
