I feel like heavy tanks need their CPs pushed back. The tiger and T3485 are soo effective for their cost and the time frame they arrive. Players should be forced to stall longer to call them in if they decide to forego teching.
You contradict yourself.
You say they are too cost efficient and then say that getting them later will fix them.
It won't.
If a unit is too cost efficient it needs a price increase, putting it back in CP only means that 2nd/another pair will come that much faster after the first one due to stacked fuel.
