What kind of resource increase did you have in mind?
Resource isn't the issue.
The issue is respectable at+good ai+ average pen (better than t34, worse than panzer 4, same as cromwell)+late game utility.
The next step is crews repairing the tanks....oh yeah
The game has to go to the opposite direction, EVEN IF the price justified it (but 110 fuel for vanilla sherman performances is a joke), sherman should lose any support role, give smoke entirepy to scott, as an incentive of balanced army composition rather than 1 unit spam...and it would be surely not the only way usf can provide smoke.
I would instantly remove he, give sherman same cromwell/panzer 4 ai, start eventually rebalancing price from there, give scott as powerful anti infantry instead.
Than a global upgrade could be evaluated, but it still end up being ez8 less armored version.
