Actually it is hunting. You get your mark and go out into a region and look for it, kill it and get rewarded. It may not be what you expect but it is within the mechanics of FFXIV. Its not a hunting simulator. Its the basics. B marks spawn every 5 seconds so it's there you just havent found it. Also you're using the term hunting too literally. When someone says they are camping a monster you don't picture them with a tent around a campfire. They are just standing there.
