Why can't Dynamic Queue and Solo Queue co-exist?
I don't think it's fair to abolish dynamic because of a few experiences because not everyone has had negative experiences with it. Especially because if I find good players in my game, i like to add them and make a party.
How about just making solo queue and dynamic queue separate? In fact you could even separate the ranking system for both and add another rank since ranked 5's isn't a thing anymore.
