Also in the Obers test, vet 0 Obers vs vet 0 Penal, the obers lost 2 and the Penal lost 6. If you can justify the penal vs volk/gren performance due to a 50 MP difference, why isnt the 100 MP difference that obers have over Penals seems to not have a similar performance differential?
The video is ill-conceived at best and deliberately misinforming at worse. The obers were not upgraded with the lmg 34 until they had already dropped to 2 models. Furthermore the vet 5 obers moved out of cover mid engagement , which until that point they were clearly winning (dropping 1 model, while penals lost 3) without the lmg34. All comparisons were also done at mid range, which makes the entire video unrepresentative of any realistic ingame situation since penals would have to close in first to get to mid range.
No one will ever not upgrade obers. Now, if the argument here is that obers should already beat penals with only their standard rifles, then the logical conclusion must be to adjust obers to do just that at vet 0 and remove the lmg upgrade.
With regard to veterancy, I'd expect obers to win already at vet 2 or 3 against vet 3 penals even without the upgrade. Vet 2 already offers all the offensive bonuses, 3 and 4 only offer more received accuracy reductions while vet 5 is sprinting.
