Right now, the nobles are always visible by the enemy team (with the indicator mark hoovering over their heads) and this promotes archery and thrown weapons to just aim at the indcator no matter if they can or cannot see the actual model (of the nobles). This makes smoke cover useless and in fact detrimential to the nobles as they cannot easly identify friends from foes (in smoke) while the opponents can always see where the nobles are.
Balancing issues of nobles asside, I think it's a small detail that could need some tweak.What I propose would have a "tick" on the last known position of the noble:
Every 5 or 6 seconds, a "tick" happens at mark the position of the noble (preventing him from hiding). that marker can stay on him for a breif moment before fading. Then another 5 or 6 seconds pass and you get a "tock" which mark the position again. This would prevent "just aim for the marker" while still giving the information the whereabouts of the nobles.
Not a bad idea, we could look into some ways to combat using the marker as an aiming point :)
