Long Range LMGs:
Currently, to take the LMG42 as an example:
http://www.coh2-stats.com/small_arms/grenadier_mg42lmg_mp
Rof multi far:
1.25
Rof multi near:
1.0
Duration multi far:
1.5
Duration multi near:
0.75
This means it has a long burst with increased rate of fire when firing at enemies that are far away and it has a shorter burst with normal rate of fire when fighting close enemies.
This is completely counter-intuitive. One would expect the LMG-gunner to do short bursts of only a few bullets when aiming at targets far away, pausing to aim the gun again and compensating the recoil whereas at short range he could do a little more spray&pray.
