BWE1: Mastery Point "orbs" in Verdant Brink
I agree. Though I think unclaimed ones show on the main map whereas claimed ones don’t, so you can check that way.
Maybe a claimed orb could get a different effect or an extra, hmm, disk of light halfway up the light column? Something to make it visible at a distance “I got that one.” I do sort of like that you can still see them, since I’ll want to help friends get to them and that’s easier if I still have a visual marker on the location.
