The MMR system for battlegrounds only works well if the population of players queueing for BGs is high. But recently its doing the opposite of what its intended to do, because the population of players queueing is so low. Let me explain.
Team one will always be 3+ premade, team two will always be 2+ premade or a combo of 2 duo groups, team three will always be a group of randoms with one person who knows what they're doing. Can you guess what team will be farmed for kills?
This isn't on my high MMR toon, this is on characters that I'm still learning how to play. I can even get a daily done because the remade groups win and then they keep coming back because they keep winning. Most people just stopped playing battlegrounds for this reason, nobody wants to come in last place 5 plus matches in a row.
Premade groups are killing off battlegrounds. Solution: Get rid of the MMR ranking system. The perfect counter balance to premade groups is already in the game, but they're all stuck in high MMR matches.
