personally i love the shotgun in halo 3 because it DOES give people an alternative to no-scoping. From my halo 2 experiences, not many people no-scoped, and then a new generation of people emerged when halo 3 came out, and the only thing that seems impressive anymore is no-scoping, which in my view, is not true sniping, and i dont think that anyone should be able to call themselves a sniper if they run around the corner and shoot someone in the head from 4 feet away.

(entire thread devoted to no-scopes)
lastly, why are you complaining unless you suck to bad at no-scoping. if you get a head shot everytime while no-scoping upclose, the sniper is better then the shotgun. because it has a longer range.
