The specific outlines would be rather annoying after a while and, Kiro wasn't literally trying to say a legit 100% wall hack. The dot gives the relative location, and once you get close enough you can pretty much tell their specific position. Maybe not an outline, but atleast the point their model is standing on. And yes it did exist back before the server went down. If you're keeping track of where you and your buddies are you wont end up killing a friendly... Unless you're running spraying with an MG, or you tunnel vision on your opponent so hard to where you can see your mate, which seems nearly impossible TO ME. Regardless though, A party system would seem nice to have but give it time for everything to come back to reloaded now.
