Well ofcourse I can't win outnumbered. I hope you read everything else which I also typed:
I did, but it doesn't put you in better light in any way.
Namely: that I could not afford to keep spending on T1 units because I had to tech. Its ostheer's main flaw imo, you simply need that 222/Pak asap otherwise you leave yourself open.
So you need early AT gun and light AT vehice vs no tech conspam why?
Because I didn't know when the M5 etc would come out and couldn't let my guard down. Yes there were some simple strategies which I could have used e.g. mg bunker; but my second mistake was in not anticipating his playstyle. This is the second time I played against pure script spam in 1v1 (which I'm relatively new to) so it was unexpected and I did not adapt in time.
That is another huge error you've made, not being able to identify opponents intentions and strat based on his loadout of commanders, bulletins and his early game choices puts you in equally disadvantaged situation as not having a pair of AT guns after 10th minute of the game. Glad you can see that yourself.
My point is that without LL, or say, mechanized assault, (if I was allied, he axis) that he couldn't have kept it up. The doctrines enable this.
Yes, that is how the doctrines are designed and intended to work.
They aren't unbeatable, lend-lease isn't even optimal doctrine and you're crippling yourself for ignoring teching with it as it can be easily anticipated and hardcountered.
And there is the other fact that t85s, easy8s etc were all restricted to tech. For the same reasons as outlined above (allowed tech skipping).
Both T34/85 and EZ8 are considerably better then their stock equivalents in both, firepower and durability.
M4C is better then T34/76, but then what isn't? Its the tier of call-in StuG, M10, dozer or command tanks, its not nearly as powerful or potent as 34/85 or EZ8, hence its not restricted.
Why the exception for LL and mech assault
Because, again, these doctrines are designed to be call-in doctrines. You're still hindering yourself if you won't tech using them, unless your opponent lost early game, which doesn't really impact late game in any way in this case, he'd picked no doctrine at all and rushed to T4 for T34 spam, you'd lost in exactly the same way, only difference being, with how much behind you were, you'd see armor on field much sooner then call-ins.
You didn't lost because of call-in doctrines, you lost because you were outplayed greatly in early game because you didn't read your opponents intentions and didn't reacted at all to his strat, call-ins had nothing to do with it.
In fact, had he teched instead, you'd be base pinned quickly by fast M5 which arrives incomparably faster then the call-in.
