That is like saying that M-42/Dhsk/120/Guards are not needed because similar units are available stock.
There is plenty of room for many units.
Here are just the listed units almost out of the game. I don’t know how it is in 1 versus 1 but in 3 after 3 and above - I do not see these units.
- Even when the M-42 had a really good buckshot shell, it was limited in team games because the ZiS-3 does a better job. And now with the destroyed ability M-42 again offside.
- DShK is not a frequent guest in the game, although not a bad unit. But at the same time, no better than Maxim - Maxim has a wider arc. The DShK has better suppression but a very small arc and a slow turning speed.
- 120 - almost unused, and therefore there has recently been a topic about it.
- Guard - unnecessary. Penaltis with PTRS completely block this unit. I see this unit once on few dozen battles, apparently due to personal preferences.
