It meets my criteria and Relics for a "super heavy". Similar CP, tech requirement, cost and as Tigers/IS-2/Persings and ost importantly limited to 1.
If tech, cost and CP requirements are the criteria, and by that criteria the Tiger/IS-2/Pershing are superheavies, then what are the ISU-152, Elefant, Jagdtiger and Tiger II? Super superheavies?
Imo IS-2/Tiger/Pershing are generalist heavies. Sturmtiger and AVRE are specialist heavies. KV-2 and Crocodile are somewhere in between. Superheavies are the tanks that are clearly one tier up in regards to durability and/or firepower, i.e. the ones listed above, although you could also make a further distinction between superheavy tank, heavy tank destroyers and heavy assault gun.
Anyway, having both a powerful offmap/loiter and a heavy in the same commander is fine in my opinion, as long as the overal power level of the commander doesn't rise too high. Jaeger Armor and the ISU commanders had their offmaps removed because it made them too versatile as a whole, not because the particular combination of two abilities was too powerful. Commanders like Lighting War or Vanguard are fine. Commanders need to be attractive and powerful to be competitive and fun.
