I don’t think this is the right option. Like Scream said, you can end some games quite quickly and having them sit around for 30 seconds is not the best. Another thought I had was maybe have a daily limit of rematches you can have against one specific person. So like you can only rematch say 30 times a day, any other rematches don’t count. That way, in order for the to continue farming, they would have to constantly go into the selector, which puts them at a higher risk of fighting other players.
