Oh, I dunno. Maybe discovering the over 200 different treasures there are to find? Rare farming? Daily Apexis Crystal Grinding? Playing in Ashran? Killing world bosses? Collecting Sumptous Fur to make cloth?
The garrison takes up a small fraction of your time unless you are micromanaging your Missions. You collect from your Mine and Garden, set up all your work orders, and then you are done until the next day. Takes like 30 minutes tops. Then you put as much time into all the other things you want to do.
This is just a no flying thread in disguise and tbh I'm surprised it hasn't been locked by now.
