MG-34 also has 5 vet levels and other mgs only 3, lets compare them
Maxim(same for dshk):
vet2 +20% suppression, +30% weapon rotation speed
vet3 +30% accuracy, +20% burst duration, +10% weapon rotation speed
MG-42:
vet2 +20% suppression, +30% weapon rotation speed
vet3 +30% accuracy, +20% burst rate of fire, +10% weapon rotation speed
.50cal:
vet2 +25% damage, +50% max range penetration, -55% set up time, +40% weapon rotation speed
vet3 +20% accuracy, +20% burst rate of fire, -40% reload
MG-34:
vet2 +20% suppression, +30% weapon rotation speed
vet3 +30% accuracy, +20% burst rate of fire, +10% weapon rotation speed
vet4 -29% received accuracy
vet5 +31.4% sight range, +20% accuracy
imo, it suffers from same problem as all okw infantry - it sucks until it gets vetted. At least its easier to vet than other mgs. Vet4 and 5 buffs look powerful, and probably close the gap between mg-34 and other mgs, but base suppression rate should be just a bit higher imo. Its the only mg right now that cant supress units in cover.
lol, I just realized that 50cal should be a beast at vet2 with that -55% set up time, too bad that it gets killed in the first engagement everytime I use it
