The bloom on the DMR really doesn't bother me at all. Sure, it is annoying if you fire it too fast, but they did tone it down from the absurd amount in the beta to something way more reasonable.

What pisses me off most is the bloom on the pistol. That in addition to the ridiculously stupid small clip size makes the weapon a last resort. I know it's a side arm, but there's no reason it should be that gimped. Congrats Bungie on making a weapon more useless than the plasma pistol. (Speaking of the plasma pistol, that is the one weapon which has had the biggest improvement, and is actually a GOOD weapon to use.)
