We had a discussion on the VainSocial Discord server (shameless advertisement: https://discord.gg/TFURa7H), wondering whether 5v5 matches are surrendered more often — and how many times.
So we took a look at data from the API and created this chart:
This is from 9 000 matches in 2.12. When analyzing, remember that one team is the winner of the game, so only half as many players surrender as there are matches ending in surrender
What do you think are the reasons that the surrender rates are like this?
