Sturms with schrecks ... this would be a dissaster. Fragile unit with 9 popcap, your minesweeper, your repair source, they are already busy enough. Giving them shrecks would also decrease their performance as combat unit.
If u want to give them shrecks make it 2 per squad, and decrease popcap (2 sturms = 18popcap really?). But I would approach other way. Leave volks as they where - meatshield squad - buff storms so they can perform as combat unit. Make Obers available earlier - expensive glorified grens at battlegroup hq without upgrades, LMG, STG unlocked with schwerer. With current changes I expect more fuel investment in flak hq, luchs and puma. Schwerer will be delayed even more and with it obers, we will end up with volks blobs and call in infantry making obers extinct.
I would agree that it would be terriable at some point, but also would be broken to be honest.
Units with AT guns (Zooks\Schreck) always will eat up vets like crazy. So this means that Sturms will be insta vet 5 after few schreck shots. And I must say, their vet is really nice. Their vet stats werent changed in patch notes. Vet 5 sturms are:
1)Unlocks medical supplies ability
2)-30% weapon cooldown -23% received accuracy
3)+25% repair rate unlocks stun grenade ability
4)-23% received accuracy +20% accuracy
5)+40% accuracy Lowers extra damage while repairing
I had sturmpios with vet 5 ones, and they could stay toe-to-toe with Shocktroops. The point is that, right know volks at least cant do shit to inf, while schrecks pios blobs (lets say 2-3 of them) with vet 5 would be able to deal insane damage up close (even with only 3 StGs) but most importantly, repair all damaged tanks without any penalties during the fight with higher speed. Thats the problem.
Not to mention that they would be able to stun any support weapons with nades.
So yeah, stumpio schreck is the worst idea.
