"..... Note that online, your debrief could affect the kill crediting of a friendly player."
For that reason I would hope that the game might include an option to pass on using this system, not that I can find anything wrong with it, just because I can imagine a lot of fliers not co-operating.
Imagine a scramble and melee at 20,000 feet. I engage an enemy and down him (well I can wish

) and this is witnessed by one other person. However, this person gets blasted in next minute and leaves the arena (as so many do) without filling out a debrief. I think this would cause a little 'tension' in Hyperlobby, don't you?
It certainly has promise for offline and perhaps squadron matches online though, a nice idea
cheers
