The MMR system is a system implemented to tend to the less experienced player base of the game Halo 5: Guardians. The system was built in the hypothetical situation where the population of the game was high. Since these systems have been added, more have been added and they have been making the game gradually worse for the community. This has led to a decline in the entire population of the game. This also affects the player base in a way that punishes players who are above average players, making matching times extremely long and giving bad experiences to players that are better. This change will maybe bring about the expansion of the current Halo 5 community until the release of the next game.
