A Comet (800 hp) that dies to 4 shots (200 damage each) and almost costs the same as a Tiger if you include the hammer tech would be utterly useless sure it has better speed and nondoc smoke/phosphor at vet1 but it will be hard to make it work vs tigers so it might only bully mediums and some infantry and gets hardcountered by heavys or tankdestroyers.
Well yes, most units arnt as good when they face their counter, why is that a problem?
Same goes for t34/85, M4A3E8, Sherman Bulldozer (both variants) (hp between 720 and 800 compared to 640 for mediums) so pretty much every single premium medium tank will have a worse time while fighting against Tigers. I think it might go that far that their cheaper counterparts will not only more efficient at fighting vs heavy tanks but also nearly as effective.
So heavy tanks cant be good vs tank destroyers, they can't be good against premium mediums, what exactly are they supposed to be good at? A heavy tank should be getting something for their high price and low mobility.
