I never got it, but I don't really care. It's just turning into full Hayabusa. My combo is Mark V helm, EOD Right SH, Hayabusa Left SH (You know that HB shoulders are badass) and Scout chest.
Yeah, if we can use them in Matchmaking in H4, they definetly need more customization options, because I'm not sure about Reach, but in H3 there were only five different Elite classes; Assault, Combat, Flight, Ascetic, and Commando.
