I used to care, I really don't care anymore. it happens so little that I rarely feel it affects my climb. sure sometimes you get the shitty 4 man premade who is toxic and feeds while blaming you but equally as often you get the 4 man who pubstomps and it doesnt matter what you did cuz you just rode the freelo.
dynamic queue isn't stopping anyone's climb and neither are premades. the game is just different now. the only issue iwth premades is usually one of them is a high elo smurf due to the inability for that high elo smurf to play in his own elo. queue times are awful and when you are against premades one of them usually pub stomps and its clear who the smurf is. even when I'm smurfing I'm like "man this guy is way too good to be in silver" and sure enough he tells me after game he is d5. it won't stop anyone's climb but it happens more often than it should.
