The balance team wanted to make them more reliable but less able to randomly wipe. They didn't achieve this at all, now they wipe even more while still being very RNG depended. It's still very hit or miss especially with the KT.
Locking them behind T4 was the right choice. But the CP requirements need to go up 2 CP. Right now they arrive too early.
The IS2 has too much armour, it needs to go down to around 330 IMO. Right now it's too hard to penetrate even for Tigers, Panthers and Kingtigers. JP4 is basically useless against it unless you have good RNG.
I think the heavy tank AOE profiles need to be slightly reduced for all heavies apart from the KT, which is still not that great overall IMO.
OKW meta is so boring now because Grand Offensive is the only viable doctrine in 1v1 and 2v2. Then again all their other doctrines are mediocre so it's not just a Grand Offensive problem. And even Grand Offensive is just good because of the Tiger.
+1
Luftwaffe is good as okw too though. 2cp elite infantry that are good at all ranges with camo plz. And whatever commander you go you can still get KT so that's not really a factor.
