Err...Crimson, I don't really think you're grabbing the concepts here. The only thing I've ever seen you write is the third person subjective, which is a third person narrative mode. What we're talking about is the differences between subjective, objective, limited and omniscient.
As a GM on the tabletop I had to use Second Person Objective nearly continuously. It is quite appropriate to describe what a character not your own sees, hears or otherwise senses. The think to avoid is describing any reaction on the part of that character. For example, when a dragon rears before the characters I would describe everything the players saw... but I would avoid adding that they feel fear and tremble before his majesty. If I've done my job describing the dragon adequately the players should feel this on their own.
One thing that is certain, some villains would be completely ruined by the third person subjective mode. In particular, those that use treachery and confidence games. I can't tell you how many times players have reacted to the narrative voice and not the character.
On a different tack, a telepath would be rather ideal. We have two brawlers and three blasters in addition to our earth mover. Generally, our group is best suited to guerilla tactics :) We're also lacking a doppelganger, a brick or paragon, and a technical expert.
