Penals - since they already have the flamethrower, which wouldn't mesh well with LMG.
The flamer is not a CQC per se, it counters green cover use and could serves as a deterrent for charging units like SPs or PGrens while the LMG rekts them at long range. Even a buffed SVT would have been a better choice
Volks - The Ostruppen comparison went out the window after the OKW re-design buffed them closer to Grens. Not to mention that Strumpios are still vastly superior for CQC and don't require an Upgrade, they won't disappear. The STG package is just a compensation for losing the Shrek - and a good one at that since they struggle with vetted/upgraded Rifles and Tommies. If you have a better idea feel free to suggest it.
Which was not a great change to begin with, the increased DPS I mean. Their original concept was some place holder AT unit intended to hold against light vehicles. SP are superior yes but there is not much point building a second one. And new volks wil struggle even more against Tommies/RM since they lost their only advantage, long range efficiency. And 2 STGs don't mean shit for that role. My idea is returning them to their original concept, something between cons and ostruppen.
Arty- All of the Arty buffs are needed - Scott, Major Arty, Tommy Flares, Etc.
Neither of them are needed now, the "omnipotent, all powerful" volk blob is dead.
RNG - There is a difference between teaching moments and computer monitor punching induced rage from random squad wipes.
That is a problem with the player for taking the game so seriously. I have tested the TM35 in game and it takes 2 models at max. I mean what the hell.
