More ideas for super tanks. I think I understand where your going now.
Step 1
You have HeavyTankShell and you have LightTankShell.
Give every other tank LightTankShells and reduce damage of it.
Ad more damage to HeavyTankShell.
Step 2
Remove all other HeavyTanks on map and replace them with LightTanks.
Step 3
Remove damage from all
bombs/shells/explosives/grenades/mines
except HeavyTankShell on material 51, 52, 53, 54.
Could have some slight damage on material 51.
Step 4
Boost damage up on HeavyTankShell on material 50, 51, 52, 53, 54. Increase explosionforce like in other example.
Step 5
Ad a Tank repairpoint on HeavyTank.
Boost it to repair HeavyTank faster and remove radius.
Step 6
Probebly tanks use same machingun, so you can't boost that one up to much, but what you can do with it is give it damage to material 39-50 and 60-76 and make it shoot more strait.
Now you have a pretty strong Tank with unlimited ammo and repair. Super powerful Shells that if not kill it move it and MG that kill whatever you aim on.
Is this close to what you had in mind?
You can for fun make knife do damage to material 54.
