Bloom is needed "Bad Boys", it's just needed.
No body likes the trigger-spamming noob running at you while jumping around, then tea-baggin your dead body. That's not skill. Pulling the trigger isn't skill.
Skill is learning how to use the weapon properly and actually timing your shots, working shooting angles with the architecture, paying attention to your sights/reticle, etc, not to mention that a gun with bloom is infinitly more realistic than a "stationary gun" that's shouldered while running/strafing sideways up a ramp or in mid-air.
Bloom requires skill. It requires patience, not the "I shot his face!!!" instinct that you have so clearly pointed out. There is a higher-level of Halo skill yet to be gained I think.
