On Isle of Thunder at the time of posting, we can't access the upper tiers of the Troll/Mogu citadel, but if you path around the edges you will stumble upon a very accessible cave that leads to one of the currently unlocked areas.
I'm not suggesting anyone do this, you might cop a ban.
At a glance, Blizzard has clearly forgotten to paste in one of the doors in the cave (the other exit is sealed correctly).
What is your take on the logic of banning players for exploring past here?
"Because you're not supposed to get in there" doesn't really provide a solid argument.
