Step 343 of the War Campaign tells me to talk to Druza to travel to Ar´Gorok. I went to Druza, but she tells me travel to Arthi is too dangerous and that portal will be open when they gain control. I´m not sure what this means, or how to progress any furter with the guide.
OK great. Perhaps you could also put a note in the quest explaining this, so that we know to come back to it. As a new player of BFA, it is a bit confusing.
