As a casual observation no one seems to realise that to upgrade Volk STG for all the squads, as well as Shrek's for 1-2 sturms is going to be expensive munitions wise, especially when you are expending fausts/grenades/mines.
Maybe increase the cost of OKW upgrades by 10-20 to force some decisions? IE The Player must choose between increasing his AI or AT by choosing each respective upgrade.
Proposal
Volk STG package costs 75 Muni instead of 60
Shreks for Sturms are 100 Munitions instead of 90.
Alternative sturm upgrade: 140 Munitions for X2 Shrek (which will dramatically decrease AI effectiveness)
Forcing the player to choose between minesweepers over shreks would also be interesting, by punishing those who attempt to spam shreks on 2-3 sturms by having no mine detection.
I still think any Shrek upgrade should be locked behind two trucks for OKW, to make racketten/Faust combo early game important.
Overall I like the changes, but we will need to see how things go.
+1 people don't understand the danger of the sturm with only 1 sherck they need 2 so even ostruppen can kill them
