OMG! If you don't have this addon and Master Plan along with it...GET IT! Get it NOW! It makes missions and Garrissons SO much easier to manage. :)
Can't seem to find it via the Curse client, so install from the website:
- Master Plan - Saves you from having to click each and every single mission when it's completed. One click to view all results, and then the rewards. Sorts the missions a little better too.
- Garrison Mission Manager - lines up the followers you need for each mission, and allows you to one-click assign who you need for the mission you want tot complete. Brilliant!
