How balanced is the KV-1 ZIS-5?
I haven't actually played it albeit I do have the "Hero" skin (blessed by gamble box) because I usually avoid the BR IV and just kinda of skipped to the T-34-85 and JS-2 too, and I've been wondering how balanced it is since in paper, it's not.
It plays at BR IV, which means it can fight against Panthers and Tigers and if uptier-ed, King Tigers and Ferdinand, which it feels kinda hopeless since it still has the 76.2mm, even if it is an upgraded version of the original cannon, and the armor is about 90mm in the front and almost full turret and 75mm on the sides and back which means you can angle, but sincerely? Fighting the big cats with only APCR and pray seems very uncomfortable of a gameplay, while it does absolutely nothing against the Ferdinand and King Tigers.
With all this yapping, the point question is, people who played it, how good is it? Should it be in a lower tier or does it make justice for its position? (Be polite you sweaty Russia mains)
