Personally I dislike when weakaura make use of a map to tell you where to go like Netlharion, Igira or Fyrakk intermission. I think it would be much more easy to have that kind of debuff already assign some kind of different markers to people so people can react with it. I think it is way better to say green markers go left and blue go right for example like the Odyn mechanic when anyway weakauras will do the same just less visually interesting.
