I would love to see a weapon that works as a Scout/Pulse Rifle + Assault Rifle An exotic that would have switchable fire modes: Full auto (in this case auto rifle) would have bonus damage vs shields just as you suggested, BUT it wouldn´t deal a lot of damage to unshielded enemies. Pulse/Scout mode would have perks enhancing precision damage or stability (this would need tinkering to not be dominant in PvP) This way you could have and amazing primary that would be PvE-focused for shielded enemies/bosses and a gun worthy of its exotic status. The only thing that would need to be done is the mode switch. It CANNOT be done the same as Murmur...too slow. It has to be a button on the controller
