Idea: Allowing Spectators in Dungeons

[Kirito]

This seems neat in theory, it'd just be a question of whether it can feasibly be done or not. Are there any other MMOs on the market that have this feature outside of special events? This could be considered a "next-gen" feature for a MMO if so, which might make it a selling point for some people. I'm not expecting it to be in at launch or anything, but if it doesn't have a high development cost, sometime down the road would be cool.

There is rarely anything that can't be done unless it is due to hardware. The only difference spectators will have from normal players would have that they can't fight, possibly transparent and possibly have limited chat. They can even categorize it like a buff.
