Here's the thing.
Last time the ban wave is for the reason of "dodging" which means creating empty games for the horde premade to benefit so that they can meet pugs in the BGs. Which sounds much closer to the "wintrading"
And now lets look into this case. As Tsirup explained as a member of the alliance premade in there, the screenshot was made after the Blacksmith fight which got us wiped when we try to win against em 15vs 15. So if your ban reason is "you should not take part in it if you dont want fight it " . then its not a proper one.
Last thing i wanna say is that players involved in this case are mostly chinese players, and the BG dodging involved are mostly EU/NA players. Apparently the players who are involved in the two cases are not treated equally. Even given the facts that the influences of the Creating empty games are much worse.
This community is a big family no matter the region where you come from, you should be treated equally. Yet its not true so far.
so dear Pottu please do things right this time because a whole lot of PVP players are watching. It's the last wow game play for most of the banned players. Please make the decision carefully and not harm the heart of a love for the vanilla wow. Since we did nothing wrong in this case.
