I just can't understand the logic of this or find any information about it. I'm finding it extremely difficult to climb in rating gaining 5-7 points a win and losing 20+ from a loss. A lot of friends I PvP with are also experiencing this issue. The MMR is very low and even winning 4 games consecutively it barely climbs compared to previous seasons. I didn't see blizzard announce an MMR wipe anywhere. It's doing to discourage mid tier players constantly being pitted against 2400+ players at 1600 MMR.
