Hi guys, In this order of Quest line for the class mount it starts at Grand Priest on Broken Shore after completing Breaching the Tomb with a Priest which I did today out 15/15 chapters done. In this order you will start the quest for the class mount;
The Speaker Awaits – needed to go back to the order hall & get a follow up quest.
The Sunken Vault – to meet Brann Bronzebeard in Azsuna (near Illidari Stand)
It will start as a scenario and to activate the console and kill the enemies who are attacking after around 3 min of role play and talk to Brann to return to Dalaran. Whenever there is a Brann in a scenario he is a very humorous dwarf he makes me laugh every time he does and do side jokes.
