Three words: Dual-wield weapons. There were some missions I felt would've benefitted from increased fire.... but not like the setup for Halo 3.

You could use both weapons at once, or choose to store your other weapon while using the current one, unlike in Halo 3 where if you wanted to go back to one weapon, you'd have to drop the second gun.
