Advantages - Nearly godly at close range.Unbreakable even with a haze/panic on it if you're stim pack is activated.
Disadvantage - Terrible at long range,and its quite hard to whoop out the battle rifle and snipe you're foe.
Increasing the range of the shotgun would do a good influence to the commando.
I feel like the commando issue has been discussed much before,so I'll not go into detail.
Reducing the range of "E" In SS,TA.
Range of E in SB is quite suitable.PIS has already talked about on the previous threads on kongregate.
I'll come up with more when I can lol.
