Tiger nerfed? Lol, that would be "nice" to see, especialy if they keep the Panther and the ISU as there are now. The necessity for an "I win" button is strong in soviets as I can see.
If it is for a change, I trully hope they eather nerf Tiger eather buff IS-2 not both actions, because we saw what this kind of shit does to balance.
IS-2's hp buffed, Tyger's - nerfed.
Most likely they're got the same hp now (1040), while KT got 1280. I do not know the numbers, so it's just speculation.
About ISU-152 and KV-2. Range nerfed to 70 (in KV case - in artillery mod). Unexpectedly, I haven't seen confirmation of Ferdinand range nerf.
