The OKW inability to defend it is another reason why the Stuka should get an HP nerf? Strange logic.
What inability to defend it? You have cheap mines, you have shreck blob, you have puma in the same building and that puma will arrive just 3-4 minutes later at worst. Its easier to defend stuka then it is to defend katiusha or even pwerfer. On top of that allies do not have burst infantry AT and good luck sending lone, unsupported tank behind OKW lines.
No, please do the math for me. You don't know the costs of teching yet you make a statement that it costs twice as much? You're still getting tanks that can directly kill infantry.
Since I feel better today(yay! no more fever!) I shall shine upon you my elementary math skills you seem to not posses:
Soviets:
120fu+85fu+25fu(because you WILL have AT nades by that time, likely molos as well, but lets skip it for now).
Which gives us 230fuel needed to get out Katiusha.
OKW:
Now, we need to save 5 fuel for the truck as OKW starts with 35 and 100 for the stuka, which gives us 105 fuel.
Lets use another healthy assumption, that conversion mun to fu will be off. OKW gets 0.66 fuel penalty, so we need to multiply cost by 1.34 rounding slightly up, which gives us: ~140fu needed.
Should I call math scientist to further explain to you why stuka is much cheaper to get then katy if for some unknown reason you can't see it yet yourself?
Why are you using the SU76 in this comparision? Nobody uses them anymore. You're just using one of the most weakest tanks as an example, should I start complaining how long it takes for the 222 to take down a t70?
1) Because its still in the same tier as katy, same as puma is in Stuka tier.
2) Because its apparently supposed to be light tank destroyer(well, no one really knows what its supposed to be, not even devs, but lets assume that role until proven otherwise), just like puma.
3) Because they have pretty much exactly same cost.
But sure, lets say T-70, which means it needs 8 shots instead of 2 that drop katy. I don't really know how does that reinforce your argument, but there you go.
