Axis have better tools to set up defensive positions. Soviet stock mortar just doesn't cut it to break through them. I see it in good position that one faction have good defences and other have optional doctrinal tools that can solve the problem.

In fact Soviet artillery was superior and more numerous IRL.

I think it is utter crap, just like other Soviet doctrines without elite infantry and vehicle call-ins. Poor faction design is poor.

Not saying that Soviets are underpowered - no. They are very good with proper doctrines, but "Not one step back" is just not one of them.

Tripwire flare anyone?

Keep two pak40 behind your tanks.

I think that halving (reducing) resource gain rate is not an option as it deny some strategies that rely on fast rush to some vehicles (fast T-34 or Ostwind). Opposite side will have plenty of time to prepare counter on it.

The problem is in possibility of skipping tiers and sit on call-ins.
There are two strategies at this moment:
A) Teching and building fast weak vehicles and try to win quick (which is kinda hard in random 4v4)
B) Saving fuel till meeting CP requrement and then rush out many vehicle call-ins

If time window between first built tier-tank and first heavy call-in would be wider, then we will see more teching and less sitting till call-ins.

So I see two solutions to that problem:
1) Increase CP requirements to late vehicle call-ins (T-34-85, IS-2, ISU-152, Tiger etc)
2) Bind call-ins to tiers in order to deny savings I mentioned in strat. B, so both strategy types have same amount of resources to spend on vehicles

Or maybe even implement both of mentioned solutions AND REDUCING RESOURCE GAIN. But then we risk not to see late vehicle call-ins at all, so there would be no point in certain commanders.
