What Cyphre and Nrom said. Making them switch group tags is going to cause all sorts of frustration from them. Like having chronus as a void was somehow "intentional because we wanted to limit attackers." Having them switch groups would make group authed gear not work unless they switched back. They'll claim that's intentional. I think I agree with Nrom. A simple hud that says "Hi, I'm hostile." A receiver in the objective that says "oshi- here's a mineral pack." a node in the hub that says "OMNOMNOM MINERALS." not. that. hard.

LEave it as is. It correlates with our threat levels, which most people are used to. And while, sure, "Threat level 5 DEFCON 1" might make sense to some, surely there are others who will see it as "Oh its just one attacker. It's cool."
Just puttin this out there; I never missed any of my 300 meter shots. I did miss a 50m right though. Popped up and i didnt even see it. freaking green silhouettes.
