Finally got my tier 9 VK, and the tank's a beast. The amount of bounces I've been getting remind me of the heydays of the KV1 and KV3. It's amazing. Even tier 10 tanks find it tough to hit the weak spots and most don't even know the weak spots.
Apart from the occasional gold toting tank, tier 10 TDs (and of course artillery on open maps), the VK B is nigh invulnerable. I cannot wait to get the top gun and do some real damage.
