The more I think about this patch the less I like it. I like the small arms fire changes but the teching cost increase raises a lot of concerns.
If you go for T4 as soviets, and decide that you need more armor to be aggressive with, teching back to T3 and getting a T34/76 is insanely expensive. Your opponent could get an elephant for that fuel cost.
I'm really concerned what the value of stock units is going to be over call-ins when the teching costs are so high. And with that, the value of commanders without armor call-ins. Especially on the soviets side, where the total teching fuel-cost is nearly double that of the germans.
valid concerns. and i'm pretty sure you will be at least partly correct.
relic is probably going to adress those issues once they arise after the patch, simply because at the moment they have no clue how the upcoming changes will affect the mid/late game. for the moment, the best advice i can give you is to enjoy a more interesting early game, play around with as many different strategies as you can come up with and then come back here to complain about the imbalances that you found. maybe relic will listen.
