Also borrowing a quote from someone else over in the Assault Engineer thread, but he pretty much nails the point on the head.
Assault Grens advantage? You mean the half of 1DPS advantage? That's miniscule, not even worth considering, and doesn't even come into play until after around 25 meters. You can literally wait a full minute and the two squads will still be going at it.
Sturmpioneers advantage is a small window at mid-range, where they actually do measurable damage, without AE's DPS overtaking theirs, which only requires them to step forward a few meters.
That few meters to step forward is very very short as a distance and that's the overall issue with Sturmpioneers and well.. just about every German unit. Shocktroops, American AE's they will jog right through the sturmpioneers mid-range window and rape face.
Even worse though, because the close range + max damage values are actually longer at "10" rather than the Sturmpioneer's "3", these SMG squads can literally sit back at a distance dealing their max damage... it logically makes no sense.
An Assault Rifle, you'd think you'd outrange your opponents with SMG's for accuracy and damage, but instead it's the other way around in this game...and that's okay by you guys? You think that's right or even fair to either side?
