Terrans aren't a melee race. For ****'s sake, we've abandoned close ranged combat about half a millenium ago. Do you think people another half a millenium from now would be using swords? Shotguns suck and they don't do jack shit. Pellets would just bounce off ****ing Zergling armour. Flame throwers have already been used and it's stupid to put it on a Goliath which has kick arse miniguns and torpedos that can rip enemies to shreads. Why ruin it with a pussy flame thrower? Oh and by the way, Firebats use two flamethrowers, one on each arm.
