Blue "looking for" icon - Always visible
I’m sure that someone will correct me if I’m wrong, but I believe that is the “Commander” icon attached to people who have invested in the squad commander training book for their character. I suspect that this icon is intended to be extra-visible so it can serve its intended purpose in the busy WvW zones.
That said, I agree that the icon can be distracting and immersion-breaking in PvE, although I’ve also seen squads used helpfully in some of the Orr zones that require greater coordination among players to be successful.
