Specator mode for FC when doing high end content?

Well i heard about a spectator mode.. but i tough it was already implemented ... But looks like its not ... it would be really nice i think being able to create a group with our FC and having spectator mode for people in the FC wanting to learn the high end content the FC is running... seeing live whats happening in the high end raids / trials etc, the FC run ... I think it would help the new player learn whats up in high end content ? and then they could start discussion with player runnig those to understand the mechanics of those fight .. or even, for the new content .. they could watch what happen and talk about what they seen and help make new tactik about it etc etc ? Really id like to see my buddy in FC watch the static raid group and help us out for new content, making new tactik, or just make new static with them so they can also go through this content ? Just a suggestion .. its my opinion

It's implemented for custom PvP matches only. I also like the idea of enabling it for PvE, though. Also not sure this is the right forum since it's labeled "website/companion app," but hopefully they'll figure it out.
