No one used in the AR in general in Halo 3, ODST, and REACH. What will the AR become? Basically the same thing in all the other previous games, just a rifle you switch in for a better weapon or used for taking down shields or destroying vehicles (which was pausible in HALO CEA)
I guess I shouldn't get to worked up about it (not that I was in the first place.) because after Halo 4, nobody will play Reach's multiplayer, so, yeah.
