It really detracts from the experience for me. So much detail in the game in a serious nature but the numbers seem a contradiction to that essence. Of course, the settings for damage numbers and enemy health bar should be two separate options. The only problem that would remain, is not knowing if the enemy you're against is receiving damage.. But that adds to the essence of immersion and danger imo. Perhaps a 'ricochet' bullet noise would resolve that issue, including hitting parts of the enemy that are armoured or not critical/weak points. This, so far, is the ONLY qualm i have with the game. make it an option, make everyone happy. Thank you Bungie!
