2)"volks have theoretically more dps at extreme range"
All the engagements never stay at max range, AND any upgrade make the squad much better at long range while further boost close range.
Volks dps: 1.94/4.94x5= 9.7/24.7
IS dps: 3.08/5.22x4= 12.32/20.88
Rifles dps: 1.84/7.66x5= 9.2/38.3
Wow a 0.5 dps difference max at a range infantry usually doesn't even stop moving
In a scenario in which rifles have already less RA.
Gamebreaking......
The DPS from that site is not very accurate, the DPS for 1 of those weapon should be closer to these values:
volksgrenadier_kar_98k_rifle_mp 4.55 4.01 3.46 3.04 2.70 2.43 2.08 1.81
tommy_lee_enfield_rifle_mp 4.77 4.59 4.27 3.98 3.72 3.48 3.17 2.89
m1_garand_rifle_rifleman_mp 6.76 5.85 4.33 3.41 2.81 2.35 1.98 1.67
riflemen_bar_30_06_light_machine_gun_mp 13.98 13.98 10.46 7.99 6.97 6.03 5.17 4.38
The VG K_98 does 12 damage so it overkills needing 7 shots to kill an entity and its DPS should be considered lower.
