I'm still confident they have to reset the ladders somehow or roll it back - there are so many "legit" teams that spam queued versus wintraders up to like 2700 rating now, a friend of mine accidentally faced some at like 2am the other day and got up to what, 2712? They could've kept going, too, but they didn't want to go above rank 1 and be mistaken for actual abusers themselves even though they had very good win/loss unlike every exploited team.
This is hoping the MMR gets reset down on the characters that abused.
