I wouldn't mind having SMGs or Pistols...as in non-hand cannon pistols. I think those are actually the only 2 firearm archetypes Destiny DOESN'T have represented. Pistols in the primary slot, SMGs in special weapons. Pistols - These would be to Hand Cannons what Scout Rifles are to Sniper Rifles, save for Pistols having a bit more range, accuracy and higher rate of fire then HCs, at the expense of obviously having less impact. SMGs - High rate of fire, low to medium impact, shorter ranged counterparts to MGs. The lower the impact, the higher the mag size. Pretty much used in medium to close quarters to put tons of fire on a single target, specifically when one has exhausted their primary ammo. The twitch/panic weapon if you will.
