Bloom this bloom that deal with it or play MLG its not hard if you can't use bloom go play griftball.The problem isn't that bloom is hard...it's just not fun.
It also potentially leads to instances where a player is carefully pacing his shots while the enemy spams and gets a lucky headshot with full bloom.
This is why the first shots should be close to perfect accuracy on most mid range weapons, it should go like so:
long range: tap fire>burst fire>spray and pray>>>melee and nade spam
mid range: burst fire>tap fire>spray and pray>>>melee and nade spam
close range: spray and pray>burst fire>tap fire>>>melee and nade spam
CQC: melee and nade spam>spray and pray>burst fire>>>tap fire
There will always be the lucky man, luck's part of the game sometimes.
