That is a fair point, perhaps it could be something that is "locked" in as you enter the dungeon or whatever, ie if you had it set to public/private when you go in, that's what it stays. Then no-one could demand that you suddenly change your settings to be public once you're inside. As seems to be general concensus though, parser isn't generally REQUIRED in anything outside of coil, except for learning/improvement purposes (or in my case general nosiness, if a fellow BLM is putting out materially more DPS than me, I'd want to know how he was doing it! )
