Ea needs to fix this game it's BRUTAL!!!

If you truly believe that, you have to believe the only reason you beat that top 10 player was because it was in your favor. Which, isn't true at all. You beat them because you outplayed them. And the lower CR player most likely outplayed you. Just because someone has a lower CR, it doesn't mean they should automatically lose. There are a ton of skilled players with a low rank. Maybe they started playing late, maybe they don't play that much. Regardless, the idea the game is choosing who wins and loses is completely false.
