Description: Replace 2GA's shotgun with the PKM.
The Rest:
First a simple examination of TTK (time to kill) is in order. The LMG can 2 tap to the head or 3 tap to the body. Using the in game fire rate of 600 shots per minute I can estimate that the TTK with pure headshots is 0.2 seconds, and the TTK with pure body shots is 0.3 seconds. This may seem good but compared to the fact that the shotgun needs one shot to kill, this means it’s TTK is based purely on the travel speed of the bullets that hit, something not even factored in to the previous calculations as TTK is generally based off the time in between when the first and last shots connect. For those of you not versed in what I said to sum it up the TTK of the shotgun is essentially 0, also known as instant. TL:DR the shotgun kills faster than the LMG. (Calculations done are based of this site
Here are some videos backing the calculations for LMG TTK. I don’t have the 2GA demo whitelist so I am not able to get videos of me 1 shotting but I have videos of myself getting one shot that should suffice and also perfectly lead into my next point. LMG Head TTK, LMG Body TTK, 1 Shot Close, 1 Shot Afar
The shotgun is a multipurpose weapon which is not at all matching the LMG and is also ridiculous considering that it’s 1 shot at close and long ranges. This renders what should be it’s opposite, the marksman rifle, useless. This is bad for a multitude of reasons. The first of which being that the current meta is undeniably snipers. This is why a strong counter is to whip out a close quarters weapon. Well when the sniper and the close quarters weapon is the same gun, it removes the need to swap which gives you an edge over the opponent. So now how does the LMG stack up on this front. Well sniping is rather hard if not utterly pointless as the only sight, the iron sight, is barely usable at even close/mid range sometimes. However to get a basic idea of how they fare I did a 1v1 where my combatant and I tried to stay at about sniping distance and one where we stayed in close quarters. While these aren’t scientific tests in any way due to the nature of finding an equal opponent being impossible the matchup still illustrates the imbalance. Close Range, Long Range. In close range it's not even a competition. While my combatant did miss it was due to the nature of the fight, not the ease of the gun. Even though they did miss as well the way in which they played shows the strength of the shotgun. The fact that you only need to hit one shot. Because of this it seems (based off of squad health) I was only able to hit a single shot to the head. Even on track to the fastest TTK possible I couldn’t win. Then in long range I couldn't even hit a shot. Yes, this was partially due to my skill but at the same time had I not had an outline to look at it would have been even more impossible to hit a shot at that range with the demo class (as it should be).
With these points in mind it should be easy for anyone to come to the conclusion that the shotgun outclasses the LMG by miles. Because of this I propose that the shotgun be stripped from 2GA as adding it to Army would be power creep. A significant problem that I don’t care to explain. Replacing the Shotgun with an LMG would ensure that the two base factions stay on an equal playing field. A very important cause that, when ignored, could lead to player number imbalances, discouraged players, and a general sense of unfairness that should be avoided in a case like this due to the nature of the game. Not to mention the fact that this weapon is on a base faction, the faction expected to have the most players with no class player caps. One extremely possible scenario is if RU started promoting the use of demo due to its power. Army would get destroyed, get mad, want to switch over and it would be discouraging for all of US.
TL:DR To sum everything up, the LMG is an okay weapon and fits perfectly for a base faction. It is a weapon that isn't good if the player isn't good but if used right can be great. The shotgun however can be great despite the player because it's simply a very good weapon. This sort of imbalance is bad so therefore 2GA should get an LMG like the m60 to replace it. The gun is really good and doesn’t belong on a base faction class.
