So then you want a vehicle that's slower than what is currently offered with less frontal protection, in a variant in which the turret is not adjustable... that will make you happy?
a vehicle that played a massive part in the battle of kursk, a vehicle thats just as good as the panzer IMO (there both split wide open with a toothpick anyways) and a vehicle that had over 3000 of them produced. not to mention it could potentially be harder to spot with a sillouhette lower than the panzer we have in game.
i believe it deserves its spot here. and its probably going to be the first tank destroyer in game if we do get it. it meets all the criteria to join the game. just a matter of modeling it.
