He stated that some tanks have 30-32k hp.......
I didnt read beyond this statement. It is a flat out fallacy. BIS tanks are around 24-25k hp. Tanks stacking some endurance are around 27-28k(stacking endurance is bad atm). I dont think its probable you have seen any 30k hp tanks, much less one with 32k hp.
