I have a Base Power of 477 in Tier 3. When try to play PVP - the game matches me to players with a Base Power of ~1,450 in Tier 4. Obviously, they always win. I played 7-8 games today and 6 of the games were with players that have Base Power 1000 more than me.
I should be matched with people who have Base Power similar to mine. What is used to match players to each other?
