Well there's yall's problem, thinking the DMR has a higher rate of fire than the pistol. No it doesn't. It has a much slower effective rate of fire. There; argument for bloom borking DMR = killed.

Also, I wish the DMR had 12 rounds like in the beta. The reason they changed it was because people were complaining about not being able to make enough kills on a single magazine. The problem was that they were all placing body shots when the gun is designed to reward those who make the effort to place headshots. Bungie even implied this several times when they talked about the DMR pre-beta.
