By that premise the Jackson could be free and work as 'intended' katitof. There is a concept of cost-effectiveness in this game. The best example is the cost of the KT.
Actually, given USF extremely heavy menpower units and rifles bleeding menpower like pigs, the fuel is never issue for USF player.
People always float fuel after first 2 vehicles, because there is just no way to sustain production with menpower bleed against opponent that isn't passive potato.
If you want jackson to have 150 fuel cost, you better give it 640 hp as well.
And, now sit down and listen to me carefully:
If a unit is losing to its HARDCOUNTER it does NOT NEED BUFF, its INTENDED that TANK loses to TANK DESTROYER.
Its simple concept, let it sink and stop being lolcake.
Why are you people always so keen on killing a tank?
Do you also think countered=wiped for infantry?
If a tank(or TD) can't operate without exposing itself to lethal danger, its already countered, you're not fighting it, its parked in the back, doing nothing. 2 ZiS guns will deter JP4 from chasing or positioning too forward.
AT doesn't need to KILL a unit to counter it, if opponent can't use the unit freely without the punishment, you already countered it in that area.
You don't expect to kill every single infantry squad you encounter, why do you think you should kill much more expensive armor?
