On the opposite end...about a year ago, I had a 2 on 1 migrate into another fight and it ended up as a 6 on 2. Didn't even notice the friendlies ID for awhile, just that there was a green guy there, and I adjusted my tactics based on the friendly. We mopped up...and it was no wonder. The friendly was Flyboy. It's really fun to get tangled up with a friendly who knows what they're doing, and communication is really not needed.
