If one side is winning, they tend to not 'give up at that point. So, there isn’t an ‘equal amount’ to be had.
The same conduct happens in much of the rest of these games, that’s part of why many pvp-based games end up with verbatim complaints regardless of playerbase size, implementation of scapegoat features (stuff easy to fault). Fighting games – 1v1 instead of 5v5 – still see similar problems.
