Replay Abuse
Bronze plays: The enemy invades my jungle, tries to kill me/steal red buff. I punish them by getting a double kill, then taking the red buff before they can take it. But because their adc was having a connection issue, remake was triggered, and they get off scott free. The MF wasn't connected until 2 seconds after remake was calculated, but she is probably not the loss of the team (since bard is bot, and MF would more than likely followed bot, even though there is an equally likely chance she could help out and kill me.)
I've seen this abuse of the remake system about 75% of the games where a remake was possible, where the people in the game use the system to get out of the kills they fed. I'm going to eat my loss (technically win, but without reward), but I am putting out this scenario for the wrath of the board to dissect and maybe agree/disagree.
I know that in higher elo, 3 minutes of DC is might as well GG, but in lower elo, the remake system is sometimes used as a mop to clean up a bad play.
