Apex arena rating system is broken

The arena ranked system is garbage and something needs to be done. I am diamond 4 and am stuck at the same AP. I find myself constantly getting more damage than my teammates (mostly because they are silver ranked) and end up losing the game because of their mistakes. Just today I got a -40 because my teammate wouldn't stop inting on the other team. This is a big number considering the average points I get for a win is 12. So I am in this constant loop of gaining 12 for my wins and losing it all with one big blow. I want a better arena ranked system so that I am put in similar skilled lobbies and not punished so hard for solo queueing because as of right now, matchmaking probably doesn't exist and I am not enjoying this game mode. I also have friends who agree that this ranked system is absolute trash. Can something please be done?
