I'm planning on doing a lot of archaeology farming towards a specific faction. I used to be very active in Cataclysm, and I am only starting to get back into archaeology with Warlords of Draenor.
I have noticed that my garrison sometimes gives out fragment hunting missions, but those are so infrequent that I cannot rely on those.
I would like to solve either Warlords of Draenor or Pandaria fragments, ideally for the crates. The faction I'd like to target is heavily mixed with other factions that greatly out-number the faction I want.
For example, If I want to gather Tol'vir fragments. It would be horribly inefficient to fly all over to do night elf dig sites when you can just solve for a crate and get Tol'vir fragments slower but more reliably.
Is there a better way to obtain specific fragments besides farming Warlords of Draenor or Pandaria world dig sites?
