Boy, this is a tough one to crack, mainly due to the way these units perform across modes.
Some people on the balance team are advocating for final tier side tech as a more equitable solution than tying heavies to all tech buildings etc.
Do people like this proposal?
Also, what (if any) further nerfs do people think would be needed in conjunction with the above?
To me a sidetech is an alternative to the obvious solution:
If a unit is too good for its cost, raise the cost. If the Tiger is too good for 230 fuel, make it 300 fuel. Then not only is it harder to field, it’s also harder to replace, so by reducing the availability of heavies you reduce their impact.
Another change I’d like to see is a revamp of the vet 2 scatter bonus of heavy tanks, which was ok back before the AoE changes but OP now.
