Well its not something youre supposed to be able to complete in the first month of play. Those who think they have to be 100% optimal at all times are not going to be having a very good time this expansion. Especially those who are used to only logging in on raid days.
With the AK grind, the AP grind, the CR grind, random Legendaries, random titanforged drops with astronomically small proc rates? Legion is going to be a high-maintenance xpac by design.
