Guild Wars 2

So I took a break for a month or two, I was wondering if dungeon selling is still dead. And by “dead” I mean “only possible if you take extreme measures to avoid griefers”.
I pretty much haven’t bothered with selling since they made the changes to instance ownership. Were there any changes?

Dungeon scene as a whole is dead. You can guess how dungeon selling is currently: cheap as hell + high possibility of getting instance stolen = not worth it

This is just my perspective but at least the dungeon selling in Arah appears to be very active. I guess that duoing is popular or doing any dungeon with a couple of guild mates and selling the remaining spots.
Solo selling I’d only do if you have fillers, especially with the longer dungeon such as Arah. But I definitely wouldn’t call it dead.
