I’ve learned a lesson from the last two expansions and that was to use the app to gain rep even though I’m not actually logging into BfA anymore due to boredom. I kick myself for not doing this during Legion. I didn’t achieve flying until the very end there since I dreaded the monotonous world quest rep grind.
Now I’ve been doing only rep missions for reps that I need for the Pathfinder Achievement. I expect when I log back in to have earned it. (whoop deedoo!) I’ve finally used up my resources so I’m done with Blizzard until the next patch comes out.
