Totally disagree. I had to stop playing Reach because of the bloom. Everyone competitive player I knew absolutely hated the bloom in Reach too which is why they stopped playing, whereas Halo 3 they still play. Being a prequel has little to do with it imo.
I think the bolt shot is OP. Decrease the range and increase the charge time by a little and it should be fine. I've had the same experience as SpaceWolf.
