People hated on it because it was very much not 3 with stuff like bloom, sprint, armor lock etc. No masterchief story another blow. Armor lock was just annoying; people would pop it to block your stuck grenade, but all you had to do was just wait until its done then you kill them with the jump you have on them. Just delayed the game and made gunplay awkward. Kind of funny when you play a reach playlist in mcc now a days, no one is picking any armor ability but sprint, rest are kind of gimmicks or just make you a target.
