Hello hello!
So this thread covers a few distinct issues, mostly around the prepatch and introduction of warbands. These should now be resolved.
There are still a few issues open, specifically relating to Dark Talon, Cobalt Assembly, Artisan Consortium, Wrathion & Sabellian though we have no specific updates to share.
From what we have seen these issues should be exceedingly rare but if you do come across more issues, please do let us know through the in-game bug reporting tool.
There is no need to make support tickets for this, as Game Masters wouldn’t be able to manually set any reputations.
