I could put there literally anything wehrmacht have, starting from free rifle nades and pfaust, ending on tanks that are much stronger then any other for the sake of argument.
No different for OKW.
So please, stop looking for excuses, your beloved faction of choice got more advantages then you think so, but you don't know because you never fight against it.
Accept asymetrical balance and play other army if you like their features more, SS won't shoot anyone for not being blind axis lovers if you play other side of the fence if you like other armies features.
You have literally no control of your own snide-snark tone do you? It's like you're stuck in some alt-reality where everyone has to provoke at least 10 people a day to earn their food. "beloved faction of choice", "SS won't shoot anyone", "blind axis lovers". You're in permanent drama mode.
And Brutus made some excellent points. Comparing demo to an AT gun that can garrison a house is... Well, it's one of your weakest arguments yet:
The pueppchen has other disadvantages to compensate for it's ueber-house ability (no green cover like ZIS/PAK, shorter range than ZIS/PAK, no barrage ability like ZIS) and you can only garrison a house if there's a house, which brings us back to demo being laid everyhere.
One point you also missed, Katitof, is that each army generally has some equivalent of what the other army has. It's not like cons have molotovs but noone else has any kind of grenade. It's not like Ost has a HT for reinforcing and noone else has a HT / reinforce point. Everyone has their own version of things. So chew on that while you're screaming "ASSYMETRICAL BALANCE!"
