So if you have 100% map completion you get nice star/compass near your name. It’s kinda cool but gives you serious disadvantage in WvW since that star is visible through walls/building. I.e. this making you unable to hide and wait for people to engage in combat with NPC camp guards and strike to their backs. Mesmers are hit twice as hard by this bug due to star clearly stating clones from real one.
PS. “LFG” icon seems to have same properties
