There is diffirence in vehicle dying in one burst that lasts in seconds while your in your given example there is considerable time sunk to perform it. I dont belive there is necessarily other things wrong with unit. And changes that were implemented in this patch are fine for me.
There is also considerable cost difference, which you ignored despite me specifically underlining it.
Luchs and T70 also have performance difference favoring T70, but T70 is also considerably more expensive.
Same thing with bofors, especially preview bofors, which is completely impotent now.
Don't blindly a-move your lights into fog of war.
