4 Man Dynamic Queues are NOT and Problem

When a four-man group queues up, they could troll the whole game or even surrender at 20. This will cause you to lose the game and there is nothing you can do about it. But, if they continue doing this, they will lose MMR and Rank. They will slowly fall until they are at Silver 5 or Gold 5, or the lowest Division in the Tier. It is hard to fall out of this because of the way Riot has made their system. But a 4 man queue will cause you to lose a game for two, but it should never affect your overall rank by much. It is just luck. Luck can carry you up a Division or two, but luck will not carry you up through mutliple tiers.
