I’m a full time collector 
Back in the day I’d raid and then go farm achievements, mounts, recipes, etc but since I am required to do other stuff outside of raid besides watch fights/ bring consumables I decided it wasn’t for me anymore so I just collect stuffs now 
Yep, more legacy content but I am working on all covenant stuff too. Anything more “difficult” than 5 man heroics I don’t do though
also I don’t like mentioning collecting without also mentioning the collector leaderboards
