or maybe you old timers could use the flag to hunt down the new players for an easy kill
I think they are talking about a tag on the roster list, not on dar or anything. Knowing and enemy play is on his 2 weeks by looking at the roster is only going to tell you which team he is on. On the other hand you easily blow a guy out of the sky, check the roster and see he is a two weeker, you could help him out, give him tips, tell him how you blew him out of the sky.
As it is now, if you want to hunt down a player all night it isn't all that hard..... ask Skyrr how
