The Iosif Stalin 2 (IS-2) & Tiger II (King Tiger)

I also would like to see more light and medium tanks ex the stuart or tank destroyers like the hellcat or slugger-the only problem about some of the jag series is no turret movement so aiming would be tough with the way we drive- just a thought

Something I overlooked that's interesting for the subject of how well the armor penetration was of the IS-2's 122mm main-gun and didn't notice until recently, maybe you number-lovers will chew it over more in-depth than I have. 

The Wiki page on the IS-2's main gun, the D25-T 122mm (M1931/37), has a table listing the various munitions and armor penetrations for the gun (references cited as the "Shirokorad A. B. - Encyclopedia of the Soviet Artillery - Mn. Harvest, 2000" and the "Ballistic Tables for Corps Guns M1931 and M1931/37 - Voenizdat NKO, 1944"). 

Perhaps someone here could compare it to one of their trusted/reliable sources for me, tell me if it's in-the-ballpark or completely-off (Stalinized).  I'd also like to see something more comprehensive and reliable to work off of on the subject of the D25T's armor penetration at various ranges than a table off of the wikipedia.

3,000 | 65 | 75
Different methods of armor penetration measurement were used in different countries / periods. Therefore, direct comparison is often impossible.

I'll try to get some up for the Tiger-II later, though I don't think anyone following this thread doubts/questions the legitimacy about the 88mm KwK's effectiveness.

If we were to get this, i think we should be tlaking some SERIOUS perks. Like for the first weeks i can see it being very common as a lot of people have vehicle points to burn. But after a while it would be nice to have it so it wasnt so affordable, in a case where a single Tiger II could turn the battle for 1 side and send the enemy running.
