Just to be clear about these matchmaking complaints
Is this about ranked or normals?
If you're complaining about having to face better players in normals, you should insead use this opportunity to learn and improve. Though I agree normals matchmaking seems absolutely fucked lately, I wouldn'd mind longer queues for better games but it's not as bad as you people make it out to be. I recently had to support a silver 2 adc against a diamond 3 draven, and we still went even in lane. It was an interesting experience and I had to push myself to make good plays to my ADC could do well
If this is ranked, I can't even begin to count the number of counterarguments I have as to why you are wrong
