Dung reward tracks locked while stories done
When the PvP reward tracks were launched, you had to complete the story modes again to unlock them, even if you’d previously completed them – I’d guess in your case you went through the dungeons long enough ago to not count.
That’s good to know, but the removal of Arah explorable mode is causing problems to some players.
Arah is not completely removed, but you’d need to run a character all the way through the original personal story to get to it (or join a party with someone else who is at the last chapter).
