Issue with comp

I play overwatch Every day. I preform extremely well. I have gathered over 7000 thousand sr points this year. I lose more then I gain because to many people Join comp to have “fun” Comp isn’t for fun. it’s for serious players. I want to be a streamer. I already would be. If it wasn’t for so many people throwing or just not trying because they want to have fun. I was a 2899 tank. I lost 900 sr because of these people well efficiently protecting my team getting kills making call outs. I stay positive with these people but they just don’t care. I made new group after new group. Some day literally everyone is throwing. Blizzard I need you to find a solution to this. This is how I support my family.
