I feel like the MMR in ranked games is so much more inconsistent now then it was before DQ.
Never before this season have I seen gold 1s in the same games as silver 5s, and every where in between. Some games you just get spanked because its a team of all High golds vs your team of low golds. and I'm sure this happens in all elos. I feel like for the most consistent ranked experience it would have to be no premades of any number. and if your Gold 5 then your games is a game full of Gold 5s until promos where you are gold 5 vs a team with gold 4s on it. I think it would be so much more balanced then this whole. Oh look a Gold 1 duoed with a silver 5 and got placed against a team of silver 1s and 2s. But the silver 5 is playing support with his Gold 1 as ADC and completely and utterly destroyed bot lane because the skill difference between a silver 1 and a gold 1 is quite significant.
TL;DR ranked is pretty unbalanced atm Imo opinion, feel free to voice your opinions as I'm curious what everyone thinks.
