Simply that in the hundreds of hours I played Halo at college LANs with different groups of people, the experience was always dominated by pistol sniping, and rushes for the sniper rifle.
Every other weapon took more skill to use effectively, and was only significantly better than the pistol in extremely specific circumstances.
AR was basically useless outside close-range, and that's not too helpful when most encounters in Halo initiate and mid-range or so.
The PR took shields down pretty quick, but couldn't finish the job in the time it took the pistol to rattle off three shots for the kill.
The plasma pistol was a decent alternative, but again, are you going to go through the effort of landing an OC shot, switching weapons and finishing, or just battle it out for the 3-quick shots?
Rockets, Sniper and Shotgun were really the only weapons anybody thought highly of aside from the pistol.
