My popular mega-thread was reported and hidden 3 times by forum trolls. The GMs brought it back twice and on the third time decided to kill it, so RIP to those 500+ comments worth of discussion. I am reposting the conclusions drawn here:
Premades are an overwhelming issue for players who want to play pickup games in WSG and AB. The solution is to create a premade vs premade bracket, and/or to limit the group queue size to 5 (already established in AV).
Premaders do not understand why puggers enjoy playing pickup games. Their only response is to tell puggers to create premades, which of course defeats the purpose of having a fun and friendly pickup game.
Blizzard has gone silent and their lack of communication is failing the community, as is their random decisions that affect PVP (such as splitting queues via time zones with absolutely no benefit to players).
Feel free to continue the discussion here. Regardless, we deserve a blue post on these conclusions. The silent treatment has to end NOW @ Blizzard.
