I think that's a fair point, but I'd say it goes both ways. Let's take your example, 3 squads of volks schrek turn the corner and shoot at a sherman, that's a 360 damage, little bit more than half health, so you retreat, and this is assuming all shots hit.
Counter example, 3 rifle squads with double zooks turn the corner and find an okw p4 and fire, so that's 6 bazooka shots, let's say half pen, that's 3 * 80 = 240 damage + 3 * 20 deflection damage = 300 total damage, so about 45% ish life. The p4 will still want to retreat, difference here, maybe one of the rifles is vet1, and attempts to snare, if it hits, p4 is screwed, if not it gets away and we're back to similar outcomes as with the volks and sherman.
I would argue, volks need that shock value because OKW doesn't have a non-doctrinal snare and raketens have relatively low range compared to other AT guns, so it kind of fits with their army composition.
And yes I'm talking from a team game perspective as well.
I disagree. I would have to have 3 riflemen squads with 6 zookas... Most players (good) should only have about 3 riflemen squads + lt/cpt and you'd be bleeding MP. If you spend all yours slots on zookas, who will kill the infantry?
For OKW, volks can screen for their more elite DPS infantry, obers+lmg, fallschims
For USF, what are the AT riflemen screening for? That's why you usually see riflemen blobs with generally more AI weapons m1919, bars, to kill the volks/elite infantry blob.
That's a core reason why volks were nerfed initially (long long time ago) because they would kill vehicles and alternate with obers to kill infantry.
In team games, you will generally see some people often skipping p4 for panther. if i skip sherman for jackson, you can clearly see the difference.
blob of volks will demolish a jackson but even with a blob of riflemen i'd say a panther is well better off. after a couple strikes on the side of a panther, most frontal shots will be deflected (assuming Axis player knows how to rear reverse vehicle).
So, that is US weak point... vehicles, but it makes USF much more micro intensive. panther and volks i feel are not.
Again, i would trade 2 zooks for a shrek anyday.
