and that doesn't means this gun is not a effective anti-tank weapon, it's an answer to the German Panther and Tiger Tank, and it has proved itself of capable destroying both Tiger and Panther, and it's frontal armor is impenetrable for Tiger I & Panther at point blank range.
please google before you write down "Not an anti-tank role" I just don't want replying the ignorance ppl's naive comment anymore
You don't have to be disrespectful about it, man. You don't get to decide who's ignorant and who isn't.
In contrast to your argument, I could just as easily say that you are ignorant, because you "assumed" in an earlier post, and I quote:
...dev want all soviet players use Ram as a Counter too axis armor and meanwhile making almost all soviet tank overpriced for it's combat capabilities.
I've never read devs saying this is what THEY wanted, so putting words into their mouths is brash, at best. Ignorant at worst.
Sticking to what you said: Yes, the IS-2 is too expensive for what you get, no doubt, but you also have to remember that, in the state of the game as it is, you can support your IS-2 in better ways than the Germans can support their Tiger.
How?
The IS-2, regardless of doctrine, can be supported by SU-85's which, excepting StuG's, is cheaper than any other German AT solution. Its also superior 1 to 1.
Given these two variables, there are more chances that IS-2 will be supported by an SU-85, which outranges Panthers and Tigers. In fact, given the economical contrasts between both factions, it is very hard for the Ostheer to field a Panther AND a Tiger at once (415 fuel). So logically, making it a little harder for the Soviet to bring an SU-85 and an IS-2 (oh look, 416 fuel!!! very similar) is not that unbalanced after all.
Now lets assume both players have battled conservatively. They have played their cards right, and th egame is VERY close. Both bring their heavy Tanks, and both have their T4 tanks... They have spent 415 and 416 fuel each. Big investment.
Unless the German player pulls an elaborate flank, the Soviet player can just take potshots at both targets, and those two targets WILL NOT be able to fire back. The German Smoke is defensive, and it will help them retreat, but NOT win the fight. Spotting scopes are very good, but they require you to be static. Same with Hull down.
Now sure, if both players just have those two tanks, the Tiger will win, most likely. Units are meant to be asymmetrical in the game, but not identical in match ups. Making it less expensive would increase the chances good soviet players can support it with SU-85's, and then the Germans have serious issues escalating that kind of firepower.
I still took the time to reply to you, though...
