Point 1) I am guessing that most people don't understand that a Sidearm uses the same type of ammo as their Primary Weapons do expecaly Pulse Rifles. and 2) that using a Sidearm will let you get to Melee range with more health. as for Edit2: i prefer HMG's over the RL or Sword as while it looks like each round from the HMG is smaller in damage they are acting like the Damage stacks per HMG burst so your target dies faster with less wasted ammo. as for the Sword I don't have one yet so no opinion yet.
