It sounds like a variation on some ideas that went away when people's idents no longer showed up on enemy icons (many many years ago) and then when kills were no longer reported on the text buffer. I like it... It's a bit of a throwback idea to when 4 guys could wing in the arena, take on everyone that came their way, and kick butt even though their dots showed on the radar 100% of the time and everyone could see their idents.
The last time the Flying Pigs did that a few years ago (roving motorcycle gang through enemy territory), 4 of us landed nearly 30 kills and guys were scrambling to chase us down. It was pretty fun.
