No-tech call-in spam + light-meta rush are heavily intertwined and are a race to the bottom, basically.
If you don't do both you will be at a severe disadvantage to somebody that abuses both.
Even if you ignore the massive fuel cost difference, the other options actually would cost you a decent amount of manpower:
- Teching up
- Buying the AT necessary to counter an (240MP-ish) light-vehicle
While you are being suckered in, your opponent is benefiting from a massive discount in manpower costs. Since manpower shortage leads to loss of field presence you are basically throwing the game.
If the opponent's full-meta playstyle is making teching prohibitive for you, of course you need to buy into a call-in commander. That's why we keep seeing the same 3 Ostheer doctrines day-in day-out.
If you think that faction X (say Ostheer) should be somehow exempt from these rules try playing USF against a decent Mechanised Assault Ostheer player with the following limitations in your playstyle:
- No stuart
- No call-ins (until you have teched up)
- (no mortars, obviously)
If the player is any decent at all, you are going to see how a full-meta Ostheer can faceroll over any non-meta USF strat. This is why all of the bullshit needs to be washed away at the same time. Not just parts of it.
Call-in doctrines and light vehicle over-dominance are the whip that's forcing every player to go for the same copy-paste build-order game-in game-out (mostly because there's only 1 decent light vehicle per faction).
I don't agree.
Call-in strat is not something people assume from the beggining.
If you had great strat and plenty of fuel, you will probably go for Panzer IV as fast as you can.
As a SU, you will try to use your early advantage to get T70 or fast rush for T34.
You don't pick Stuge E, Puma, Sherman or KV1 when you have advantage. When you have one, you tech.
On the other hand, your opponent who is on a backfoot can stay in game only thanks to call ins (Ostwind, M10, Stug E, Puma, KV, Sherman etc).
IMO call ins are your last chance to stay in game when early game wasn't for you.
Now, if you force all call ins for tech what chances for staying in game players on a backfoot would have? None.
Call ins give great opportunity to strike back when losing, to stay in game, give a chance to survive and win. Without call ins game would be boring AF.
They are "emergency" commanders mostly and it's really good there are such.
It gives great taste when player has a chance to stay in game thanks to call ins.
Without them we wouldn't see like 90% of epic comebacks we saw.
