Not saying you don't, however, the way it is represented in AH is if I shoot and strike a friendly I take the damage, that is not how it is in combat.
I do agree with your points Traveler, and think that if it weren't for bad apples, it probably would be great for gameplay. Who knows better about fratricide/blue on blue than you and other vets posting here about it. I just think that the negatives would outweigh the positives, I can think of a number of players banned over the years that would love to rejoin just to shoot down and grief friendlies for as long as they could before being ejected - then getting a newIP/VPN/Account and doing it all over again. Just one or two idiots would have the game in an uproar in a day or two, I'd bet it all on that.
Imagine all the work put in for an FSO or major Scenario, and just one tard could fry the entire event by blasting friendlies in the back. Again, it'd only take one to ruin the entire event, or MA for a day, and it'd be a repeatable stunt with the anonymity tools anyone can get for a few bucks.
Nightmare is what it'd be, hands down, and not because it's a bad concept IMO, but only because it would be FAR to open to abuse, and it would give griefers a new and major way to screw with things.
