OKW still has a 300 MP unit, i.e. St.Ps, as the starting unit. Soviets begin with a 170 MP unit that's almost half of it. OKW has now free flame nades on VGs so make them OKW's starter. Esp. the combo of St.Ps and scout cars is in favour for OKW. Repair is much cheaper than replacements. And other factions don't have a 0 fuel vehicle.
Btw, St.Ps have 60 dps in close range and have almost the same stats as RF in mid range or Cons.
I think VGs would be much more in line with other factions.
