No it not.
Your personal utter lack of ability to properly utilize a unit is not an accurate indicator of units balance.
That is simply incorrect:
223 cost 320 manpower and 30 fuel and a pop of 4.
If one manages to keep it on fuel point it will return 30 fuel in 4.3 minutes but it will still not return the 320 manpower or the pop bleed. In sort Opel and Zis truck are cheaper cost no fuel and have non pop.
They are far more cost efficient.
Most people who play the game know that delaying one's vehicles by 4+minutes can be devastating.
Thank you for confirming what I've said.
No idea why you think its still wrong tho.
Also, Opel and ZiS truck can't defend themselves fron infantry harass nor can they detect vehicle coming their way nor can they heal nearby infantry to keep field presence/diminish bleed.
Again, your personal lack of unit understanding and how to properly utilize it is not an indicator of bad balance or design.
And if you compare it with other micro light it too expensive for what it does
If you heed your advise here and compare it with others, you'll find out not a single one of the others does so many things and not a single one of others boosts your resources.
OKW do not need a vehicle to fight infatry and if they want to they can already use the kubel. They need a vehicle to fight enemy micro light like WC51/UC/M3A3 or counter to sniper.
OKW have T0 ATG.
In sort:
"It tries to do too many thing at the same time and thus is average (if not up) in all of them."
I don't know what's so hard for you to understand here.
Again, your personal utter lack of ability to properly utilize a unit is not an accurate indicator of units balance.
The unit does EXACTLY what its supposed to do within the context of its army and the tools that army has during its timing.
You've said it yourself, if you need combat unit, get kubel. 221/3 is NOT primary combatant, never was supposed to be and never will be and most certainly, it isn't an AT vehicle, you trying to use it to counter vehicles might be the root of the problem why you struggle so much with understanding the units role when you keep using it incorrectly like that.
