Exactly what the title says. I played a game just now, a 2vs2 ranked. My ally succumed to the combined pressure of my opponents but I won the game thanks to super fast Burgandian Paladins and a hole in his woodline. I had seen that my elo increased by 18 points, but what about the other 3?
I am curious about this too, I know the opponents still lose normal elo amount they would have lost anyway, but I don’t know what happens to the elo of the defeated/resigned teammate if the game is won
Basically it all works as if your ally never resigned, even for your ally. Enemies lost normal amount of elo and your ally gained elo.
