If you lose a match to evenly matched team, make the loss no more than 10 points. If you win vs. such a team, make the gain no more than ten points. If you defeat better people, make the difference 20. So on and so forth. What I've seen in PvP ranked is that no matter what, I am losing more points from losses than I gain from wins, and it is so statistically improbable for me to be always facing better players in PvP that account for my losses that I can tell the ranking system unfairly punishes losses and does not properly reward wins. This needs to be fixed because it's imprisoning many in the ranking system in a downward spiral.
