Laser smg sounds quite weird like this, but i have to say, energy weapons are very limited compared to others firearms: laser pistol, plasma pistol, laser rifle, plasma rifle. Some small variations with ext.capacity and such, but still far from small guns quantity. You could also say that big guns are limited too, but those allow more various 'builds' (differents burster, rocketer, flamer). Today, in energy gun you have almost only sniper-type characters. Adding Energy SMG can be a way to explore to change it.
Of course, it will be difficult to add new weapons for both balance and technical reasons. And before all, because this game is made to be as close as possible to the original series, which is why we like it.
