Didn't play alpha, but it sounds like they did adjust the resources after the lockdown change.
Also, if it's balanced then I don't think it's an issue.
I'm glad some of the suggestions earlier in this thread haven't been taken up. I really don't want to see Brits in CoH2.
Back in alpha trucks boosted income of points to normal 100% level, but all other points gave only 1/3.
This led to extremely boring and cheap meta of locking down 3 sectors, being incredibly campy, ignoring all the map and going constantly for opponents cut off.
The change and system we have now makes map control as important for OKW as for other factions, so camping is not as rewarding anymore and you can still manage your resource by the conversion truck.
In short, what we have now is incomparably better then what we had in alpha.
