I hate: * That they nerfed all the forrunner weapons within a couple of weeks after release *That they couldn't have come up with just 2 more specializations to fill in those missing Tactical Package and Weapon Skin slots *The "ball" in Grifball DOESN'T EXPLODE WHEN YOU SCORE! *The lack of Assault *NO VAMPIRIC DRAIN* SETTING IN CUSTOM GAMES! *The pistol you use when carrying the flag in CTF is NOT the one you had equipped at the time, even when using the Magnum's skin!
*Each melee kill refills your shield if it's enabled
