I'm sorry but could you define a "super heavy"?
Are the Elefant, JT, ISU-152, KV2 and Sturmtiger super heavies or something?
Or do that Tiger, KT, KV-1 and IS2 count as well?
Cause a lot of people also count the Panther as a heavy tank while the game says it's a medium one and I'm just getting confused by what people mean exactly.
Super heavy vehicles is the term used by Relic to describe late vehicles limited to 1. (yes valentine and command PzIV does not count).
There are different type of Super heavy vehicles like:
Tanks as main battle tank
Assault guns
Tank destroyers
The suggestion is mostly about super heavy Tanks (Pershing, Tiger, IS-2, KV-2 and maybe KT, C. Panther, Churchill) but I would personally implement to heavy Tanks like: KV-1, KV-2 and Churchill since these units are imo problematic also.
