BW this is why you need to add a expertise requeriment for ranked pvp. You got this guy who created the thread, and hundreds of other people who are practically clueless (may include trolls) about ranked pvp, and they might not know that their actions impact on others.
For preseason I dont really care who queues, I even encourage pvers to Q, as long as it pops.... whatever its about the comms. But for multiple seasons you have allowed Pvers and clueless people (add trolls too) to ruin ranked pvp, and I´ve seen many win traders throwing matches in pve gear, across multiple servers, using their other toons, you might figure why (hope so).
So for S4 the best thing after not doing anything significant for ranked PVP or actually any PVP at all, with patch 3.0, 3.0.1 and possible 3.0.2, WILL BE ADDING EXPERTISE (2018) REQUERIMENT for ranked solo and grouped. It might improve the quality of games and also the feedback.
Hope you read this BW and sry for poor engrish.
