Yeah sure. Make it like PzIV but better. Don't be silly...
Wow your pro soviet bias is so evident in the last few posts ... it leaves no doubt that there can be no reasoning with you. Why don't you haunt the other threads on whining for more t34 and is2 buffs instead of worrying about panthers.
Again Panther is SIX HUNDRED (600) man power and 135 fuel, requires T4 building which in turn requires the battle phase 3 upgrade. That even you will agree is quite a lot of resources for a tank which costs almost as 2 Panzer4's to produce factoring in the tech costs.
For the amount of resources spent I expect a panther to be MUCH better than a panzer 4 in the anti infantry and especially the AT role.
I think its only fair panther gets a manpower reduction with a slight fuel increase. Right now with the stupid new increased vehicle pop cap its very hard to save up enough mp to get the panther.
