This is the best doctine to counter double USF. Coz it counters P47s by not having tanks LOL )) Airborne by LMGs blob + strafe. Ambulance positions. SO they go back to their very base as normal faction without benefits.
So many USF players just cry just bitter CRY and its FUN!
T 34-85s need as much earlier as posible. thats the point. They have immense impact on the game. "Your system" doesn't solve this problem.
As wehrmacht I always build ONE tiger only. So you system wouldn't work for me. And so on.
As Whermaht player IS2 is in good spot. Powerful heavy tank. If you pic up wrong doctrine and cant buld Panther Is2 gona blid you up. Problem that it comes with Incendiary barrage and shocks so you cant swarm it with PAKs well and PAKs are weak now.
Vs USF I never teching more than Tier 2 before realy late game coz all vehicles would meet sudden death from quantity and mines you can never save it as USF does.Only if you were able to withstand up to late game you may try
