Solutions:
- Increased survivability: that includes both the puma and the flak HT. Extremely vulnerable to oorahnade and Stuart. Increasing their hitpoints will assure the OKW player that it is not a total waste of resources and a huge risk. At least you could be able to play defensively with these units.
- Significant cost reduction: Both the puma and flakHT could be made cheaper so losing them (which is very likely after the latest patches) would be more forgiving.
- StukaZuPuss: The cooldown is way too long for a barrage which is mostly hit or miss (unlike the Nebel, Kat) . Its performance does not justify the current cost.
- Remove the fuel penalty: There, that solves all the problem and shortcomings.
