All right so I have been away from Blitz forums for a loong while beta testing WoT Generals and I came back and saw this Panzer II J frenzy. Now since a 100 lucky and talented players will be receiving this amazing tank, I will tell the rest of you on how to take it down on the battlefield.
Firstly here are its Blitz in-game stats:

DO NOT ATTACK IT FROM THE FRONT!!!!
Like all tanks, the Panzer II J's frontal armor is stronger than the rest of the tank, so try flanking it. It will be relatively easy to get around the Panzer if you aren't driving a DW2 or a TD since the Pz II J is a very slow beast. It barely reaches that top speed of 31 km/h and its traverse is mediocre. You have a better chance of getting through 50mm of armor instead of 80mm.
As seen below, it is much easier to penetrate it when you have the flat side and rear armor of the Panzer II J facing you.
And yes don't be afraid to load the GOLD!
By the way this thing hates tank destroyers, especially ones that are fully upgraded. Also don't be afraid, the Panzer II J has a poor gun for its tier 1 in a tier 4 battles.....
... so when you see one, always show your frontal armor towards it, so the Panzer II J wont be able to penetrate you forcing the Panzer II J drivers to load gold which will lead to very high costs.
Oh and all you T18 sealclubbers, the Panzer II J can pen you frontally even without gold ammo.
