I really like the gun so obviously I am going to say that the gun is awesome. But I also like the battle rifle, concussion, Sniper. And they are all good guns and not just the DMR.
Why does it take that long to release it?
Also I agree with the OP Halo has disappointed me a few times don't get me wrong though I like the story line and where they are going with Spartan Ops. It's just that there are too many problems with Halo at the moment :/
