Draenor's Last Stand

Note that this is an achievement for completing the daily objectives, not just doing each one once. You have to complete an objective while you have the daily quest from the Tanaan quest table to get credit. So the fastest you could possibly complete this would be in seven days, but that requires you to not get offered any repeats, which is pretty unlikely when you're only missing one or two. Realistically, this achievement will take 2-3 weeks or more.

I was wondering if anyone else has been having the same issue as me, for weeks, the only one I've needed for this achievement has been Ruins of Kra'nak, but it never seems to offer it to me!

Notice that not doing any of the two at the table won't change them tomorrow, so even if non of them is needed by you just do one so you get new 2 next day.
