Some of the suggestions you mentioned in your poll will never come true for obvious reasons. If you want to help suggest realistic and logical solutions so we can take it seriously. Also, after the update some things regarding the awards will change so probably more people will be motivated to queue for 3v3.
Most of the times it's a matter of skill. Even if you're low geared but you're decent with your class you can fight opponents face to face. Of course if half team is afk or if they start whining for how "bad" is their team you're doomed to lose but at least you can try find a premade group and I am sure that then you will manage win few BGs.
Log-in with your game account at http://cp.pandawow.ru/en.html , select realm, go at your characters and choose function "Repair". Also, make sure that your character must be offline.
Let me know if it worked.
About the ban system suggestion, Zeox already made a change and increased the amount of gold coins you need to pay to unban/unmute your account.
[spoiler=Cost of unban & unmute]
Service: before -> now.
Unban: 15 -> 30 gold coins per day.
Unmute: 50 -> 100 gold coins.
Also, about the question for the new arena season I have already talked with Zeox about it and he said that arena season 6 will begin after the upcoming update which is planned in this week if I am not mistaken or couple weeks after the update.
Try bandicam.
Also, I want to state that some players in the list are already banned for other violations or they already got banned for using pqr and ban expired.
Well, the truth is that if pandawow had "pqr anti cheat system" implemented in live servers the administration would have so much profit from the unbans and of course you the players would face less pqr users so as you understand both administration and community wants this system implemented as soon as possible but seems impossible to script it or at least very hard.
