The KV-1 is just 120 Fuel though, the Panzer IV is 125, the T-34/85 is 130/140. Why does the Panther need such a price gap against the KV-1 in particular, if the T-34/85's price is only a marginal cost increase over the Panzer IV for significant performance increase? The Panther should be priced at around 145 and have it's gun accuracy at range fixed.
You might want to actually play the game.
Or at the very least keep up with recent patches and notes.
KV-1 is 145.
