Their is still not a single good fucking argument why volks with shreks is unbalanced safe for its boring seeing them every game. if they put on the pio's they don't have the durability to properly support the badly outnumbered panther/jagd in defeating 85/e8 spam.
if you wish this the puma is going to need a penetration value similarly to m10 otherwise its borderline impossible to counter medium armor spam.
Osth counters medium armor spam just fine with PGs and Paks. Why not do the same for OKW by giving SturmPios double shreks and buff the Raket?
