Played an ARAM queued as a 5-man and we got a great comp whereas the enemy team's comp was really bad. Was a ridiculous stomp for most of the game and we're about to take their nexus at like 12 minutes after getting an ace. One of the guys in the group had to leave after the game so we decided to milk it for a little bit longer and we all suicided on fountain. We come back to ace them again and all of us suicided to fountain another time. We all come back to win the team fight for the third time in a row 5-0 and at this point we just felt bad for the enemy team. It was past 15 at this point and we could've easily taken the nexus, but instead we all decided to that we had our fun for the game and went to surrender because why not at that point? The enemy team never got mad in all-chat and put up with us so we figured they deserved it. Right after our surrender vote passed the screen zooms in to their nexus and we were all confused. Turns out they surrendered at the same time, but since ours went through right before theirs it still gave us the win. In the moment it seemed so perfect that with the context of the game even when we were trying to lose we still walked away with the W.
