That was one of the main problems with the JT. It was good on every single map, even on maps where it should've been at a disadvantage (urban or forested areas). Its ability to ignore shot-blockers made it OP in team games. It behaves more like the Elefant now, potent in certain environments and when supported.
Not all commanders can be equally valuable, although it should be that way. There are doctrines which can be useful in any circumstance and some niche ones that fit certain situations.
This is a shrek thread but with JT there is hardly a reason to inveset 430~ish fuel in JT anymore except langres maybe....
Shreks are potent but OKW has no anti-armor that does not wipe in to single sherman HE round that does not spend fuel....
Again, all results of a failed faction design.
