also, to be honest, they need obers to scale up against late game infantry, except for the fact that obers are non doctrinal and lmg34 is too damn effective.
Obers outscale all other late game infantry currently, by far. This is mostly due to them receiving two -29% received accuracy modifiers through vet, stacked on top of their base -30%.
For comparison, PGrens get one -29% modifier while having a base of -20%.
The LMG DPS would (probably) be fine if they didn't become immune to bullets at high vet.
