Zero bloom gives Reach the more HALO effect.
Taking away bloom does indeed add the illusion of skill that having bloom takes away. A perfect shot can not get a kill because when bloom happens, the shot can go ANYWHERE in that reticule. Zero bloom shows who does indeed have the better shot. Not only does it show that you have the better shot, it increases the skill gap of the game.
Reach isn't Halo. Bloom isn't Halo.
Zero Bloom is Halo.
