Semi casual player on Arena and I hop on to test deck ideas before putting them together in paper for the LGS. Its decently annoying when i cant even get a game in because everyone is leaving matches either instantly or within the first 5 moves. I cant practice a deck that way. I believe something could be implemented sort of copying League. Cant surrender until after so many turns and anyone who leaves the game before that turn limit by either manually closing it or disconnecting faces a penalty when trying to find new matches that stack for each offense. Im hoping that would fix the issue here seeing as i dont see any other way to solve that issue.
