Command panther almost costs as much as a allied heavy tank, or even a Tiger I. It even locks OKM out of KT.
Fair to say that Command panther is better than KT and its call-in logic is the most broken of it.
SU85 self spots for itslef too but thats none of my business...
Meanwhile SU85 has 2/3 the health of panther, no armor or anti infantry capability to speak of, is a lot slower, and doesn't have a turret but ok.
But command panther would be perfectly fine IMO if it didn't benefit from the call-in aspect (which should probably be the case for all other heavies too).
