Do i wish i could continue to walk around with my hand cannon shotgun and sword? yes, i do but its not THAT bad. Think of it like this: since there is no "special" weapons any more, and power weapons can be anywhere from point blank range burst damage, to super long range precision damage and players will now have 2 primaries (think along the lines of bringing a AR / SMG around while also having a scout rifle or something). That allows for a long range and close / mid range weapons at the same time with power weapons being for when something really needs to die at w /e range you have the weapon for. Also this will be something built into the game from the start and not like a change in a patch, meaning that bungie will balance all PvE content around having 1 sniper shotgun rocket sword grenade launcher etc. that is for heavy damage and then all primary damage outside of that. Meaning that they can not make bosses have such insane amounts of health that they can survive a barrage of constant sniper and rocket fire while primaries are for ads. To put it into destiny 1 raid / strike scenarios, The boss can be designed to be fought mainly with primary weapons with maybe some windows to burn heavy ammo instead of being designed to be able to survive a never ending stream of special and heavy ammo with primary ammo being not worth shooting at the boss. At least that is one way it could be handled in PvE, another way would be more bosses like oryx that are damaged through mechanics rather than player fire, though i hope that is not the case for all bosses. Normal mobs shouldn't be a problem either way, because having 2 primaries against normal enemies will be more than enough to take them out.
