Dynamic Queue, which is essentially flex queue, has essentially been around for the entire season.
So many players have had their MMR raised in premades that the flex ladder should take over the current ladder and the solo ladder should be new [and potentially solo only? That's the dream]
I think seeding both off of DQ is fine, as long as it actually is seeding. If you're gold now you should start your placements in gold. If you're DQ boosted to gold you then shit the bed and get placed in silver after going terribly in placements.
If they were boosted up, they will drop like a rock in solo/duo. Trust me, I've played with legit boosted players on my team and they have no clue how to play. They will constantly lose games for their team as it's essentially a 4 v 5 as they can't compete in their current elo. It is fine as it is.
