Well the fact of the mater is that the KV-1 was more heavily armored than the KV-85 because the KV-85 used a IS-1 turret and gun on a KV1S Chassis, which was lighter and less heavily armored, thus faster (which the KV-85 is compared to KV-1 in game).
Ok i like that idea too , but wouldn't that be sort of weird, I mean armor usually you know, protects, not just makes things heavier.
while the people who want to waste munis will, maybe they'll get there munis' worth, maybe not.
