I play on PC and when I join my friend & raid with him as a guest I do not get xp for my Advisory. Even when we do champion raids i get nothing. When I host he does get Advisory Xp.
So with the nurse's nerf, with the add-on to blink a 3rd time, I think it kind of also nerfs the perk A Nurse's Calling for the nurse specifically I think. Maybe in the ad on description you don't need to see where you land if you can see a survivors aura that is healing or something?
