Intelligent/productive replies would be far more preferable to mindless comments ) Honestly if you think this is a troll thread you're pretty stupid considering there is obviously solid basis behind this, I wouldn't waste time on it otherwise. I am curious to hear feedback as to whether this is actually even the problem or if I've taken the wrong approach, perhaps tiger have an armour value bug or something which means they don't bounce hits, I dunno?
The pak has armor penetration 210/200/190.
The Zis has armor penetration 200/190/180.
All soviet tanks have less armor than their equivalent axis tank except for the IS-2. The Zis bounces shots much more on everything.
Basically everything you are saying is wrong.
