is there any evidence dynamic queue led to statistically significant boosting?
I am no fan of dynamic queue but I think we should be evidence based.
Is there statistical evidence that shows plat, diamond and master is filled with boosteds?
If the high elos are filled with boosteds, then you'd expect a higher proportion of the player base in these elos than previously.
Has that happened?
To the best of my knowledge, it hasn't. It's still true that only 5% of all players are diamond+.
