add the ability to see the full skill bar of a target in observer mode and also the ability to see it's conditions , hexes enchantments and energy bar... this will help very much for later understanding of the problems ur guild may have met during ur gvg \ HA... it will also let you copy (and im gonna say why it's ok) the observed target more easily... course some will this will make it too easy to copy a target skill bar. BUT i say you can actually copy it right now anyway... you just observe a target for long enough and then you can see which skills it uses... thus copy them... this will just be easier and faster method that wont make any new "exploit"... also the ability to see the target energy bar will make it easier for a leader to see when and why his monks had problems with energy... (good for starters in gvg combat)
this shouldnt be too hard for the guys in arena net to make real i belive...
i think this will eventually become true anyway

what you think?
