Ive noticed that vendors on my Mammoth Tundra vendors won’t respond if the party leader are alliance in M+ dungeon.
I always pop my vendor mount before we start, but i can’t click on my vendors. (They are orange) But if party leader are in same faction as me it works…
I supposed is one of the small things it makes sense to not work properly with the first version of cross-faction. This proves Blizzard’s cautious approach is right. Start cross-faction only for limited things and expand it on the next patches after fixing all those problems.
