Hi all;I like fighting the IS2 actually. It's like fighting a real IS2 but the issue is that the tiger-IS2 relationship is ruined. The IS2 is a better version of the tiger in terms of armour, speed, turret traverse. The tiger is better in terms of reload speed only. I believe that the best way to fix the IS2 is to give it a reload time of 9 seconds like last time but higher damage (Maybe 200?). Other than that I'm fine with it, though it can be annoying to see multiple shells bounce off the IS2. Check out the latest replay I uploaded from my profile. You can see that me and my teammate used a bunch of pak40s to kill a bunch of IS2. The armour is only a problem if RNG decides to mess with you.
I want to discuss about IS-2 frontal armor that in my opinion is too heavy, that means that medium tanks and paks have serious troubles to penetrate it.
In this case, you can see in the video that I find an IS-2 self repairing and can't shoot at me (glitch) but it shows how strong is its frontal armor.
2 Tigers + Pak(vet2) shooting at him seems like tickling him, the help of a jagdtiger was needed to kill the tank (you will see long distance shoots coming from south). It was thanks to the Jagdtiger that we could finish the job. Despite of that, it took over 1 minute to kill an inmobile target with 4 AT cannons.
TLDR
The IS2 may need a longer reload time but higher damage. Armour is fine.
