You just proved my point, you want them to be shit-tier so you have an easier time fighting that faction.
No I am advocating "Asymmetrical Balance" as it stands the Bazookas arent a counter to anything but light vehicles. You cannot cost effectivly blob a P4 to death because it will mutilate your riflemen.
This is fine. Its the way it is. You cant just A move a blob at a tank. But they can offer supporting damage.
Even if they did nerf the Shrek down to bazooka levels or just slightly better then it couldnt counter armor in a blob like they currently enjoy today. And due to the lower level of all Armor that isnt Axis it would still perform better then a Bazooka can.
What are the alternatives? Its clearly a problem. You dont want its accuracy to go down, you dont want its DPS to go down, you dont want its penetration to go down, you dont want it to not be affected by Veterancy. Sounds like your happy with the Shrek the way it is. It is incredibly stupid that you need to rely on the RNG of a Scott or a Doctrine (Bulldozer) to fight on even terms against massed Shreks.
What is your idea? Buff the crap out of Bazookas to make them like Shreks and see the same Problem on the Allied side?
