Because why not indulge in some OP play? I would love to see a crucible match type (or as an option for some PVE missions) where guardians could spray and play with dual wield sidearms in exchange for no grenades or a trickle melee/super charge. I know it's been done before with Halo, but seeing a hunter roll out of a shadestep unloading two sidearms would be devastating!!
