Hi, just yesterday I started to do quests on Broken Isle, especially I started in High Mountains.
The wiki told me to start mining any other ore, like Leystone ore. So I did follow and found this, (1st Picture, Torn Journal Page)
I did my research, it will lead me to the starting of the Legion Mining. But, somehow it can't take me there and I didn't have the Level 1 Legion Mining Requirment, as the players told me to.
Another way that the other players told me to is finding the Legion Mining on the New Dalaran. So, when I talked for training, it only gave me the Outland Mining. (2nd Picture)
So this is my problem now since I need to farm most of the ores for my blacksmithing.
