Remake System (Needs Improvement) - Here's an Idea
Story: Played a Ranked game where someone connected to the game, immediately disconnected and afk'd for 9 minutes. The player then reconnected and refused to surrender essentially just wasting everyone's time. Because he had already connected once, the option to "remake" was unavailable to us and we suffered an unavoidable LP loss.
Proposition: I'd like to suggest that you add an extra "check" for afks in which the remake option remains available as long as the person hasn't left fountain in those 3 minutes. (even if they have connected to the game)
I believe that could be a good potential fix to the issue and would help prevent anyone else from experiencing such an aggravating loss. (My friend was actually in their promos during that game...)
