I have only group queued for WSG like twice and without voice chat. It was a waste of time and we ended up fighting and destroying the ally pug group while trying to land a game with the ally premade at that time while they were destroying a horde pug rotation. I almost never premade. IMO the server is not large enough for it. Over the past 6 months, many players on both sides have queued up and either lost to an Arcanum premade or an alliance premade (Capture, Crypton, etc..) only to never queue again. Every week you see some new horde queue up once or twice never to queue ever again. Over time we have pushed enough people away to the point where they don't queue and if they want to play pug vs pug they just goto Nost.
WSG is especially bad for pug vs premade. At least in horde AB pugs (of which we'll only queue when Armazor spams our world chat on a non-weekend) we can get 1 node and made an honor tick or two. You don't even get that in WSG. Same goes for the Alliance. The horde pug in the current meta generally beats the ally pugs because the only people that have stuck around are tenacious enough to deal with the bullshit. Most undergeared horde has been permanently pushed away from the WSG queue so what's left are the horde puggers that are a hair more hungry than their Alliance counterparts and we usually beat them. Overtime I assume its the same with the Allies who were pushed away from the server or the queue earlier on in the history of the server at the previous WSG Horde premades. I don't know but I assume as I've heard enough of it from guys who never pvp anymore or who have quit the server entirely citing wsg enivornmental exploitation or the ugly premade scene in general (RIP Victore, Assistant, Gooche, Khano, Hamasaurus, and many others)
And no offence to anyone trying to premade, its a part of the game and a vital one to staying interested and acquiring raid gear. It's just the population problem has compounded into a pvp ecology that cannot flourish with giant premade animals stomping around the environment crushing the smaller plants and animals - never given a chance to grow or even have fun.
