H:CE pistol - "Derp. We made a pistol unrealistically strong. Hmm, lets nerf the -blam!- out of the pistol even if it ruins gameplay"
BR - "We are the smart! Its the pistol, but it takes 1/3 of a shot more to kill someone! OH AND WE WILL MAKE IT POWER WEAPON! Who needs skill when Halo is just a race to power weapons"
BR - "Well, since we suck -blam!- at balancing but have hordes of fans due to live, we will nerf the BR ever so slightly. No more hitscan"
DMR - "Well, 3 round burst is disgusting and a detriment to the game, so is having the BR as a power weapon. Lets give Halo players the pistol, but nerf it to the ground. 5SK, oh and bloom. Oh and armor abilities. HUEHEUEHUEHUEHEUHEHUEHEUEH"
