ok first of 4-5 Jacksons 
Second off in the previous patch with said 4-5 jacksons how did you manage the Obers and shreck blobs? I have never sworn by any particular faction, I love playing them all (too bad I'm a hipster and couldnt bring myself to play OKW much the past few months
) but in a 1v1 or 2v2 even match, It was really hard to deal with the behemoth that was. At least now Allies can consistently deal with the tank rather than praying to the RNG gods and hoping to penetrate. See we all want Consistent influence-able play (reason why nobody likes plane crashes), With the prior armor the glass cannons of Jacksons were very inconsistent and made it frustrating to play against. Further more nothing short of an IS2 did reliable damage to it meaning that even if you try to counter it appropriately it was still a huge uphill battle (there is a video of a KT driving into a mine in front of 4 Zis guns and killing them).
Blitz was a terribly unfair ability that did not deserve to be on a super heavy tank. Blitz single-handedly countered jacksons.
This patch in terms of the KT made it countering it more influence-able and got rid of the ridiculous Blitz mechanic which allowed Terrible play go unpunished.
The KT still is a monster of a tank, you just now have to play well with it now like all tanks
I saw the video with the Zis 76mms and Mine truth is that when you see it as someone with low knowledge of the game it looks ridicilous. But the AT gun is tier 2 and it is ment to deal with medium tanks and light vehicles. King Tiger is a HEAVY TANK that was meant to do this! When you have low tier AT gun you can't expect it to counter a lategame Heavy Tank that is basicaly the pinacle of what this faction has to offer. Not to mention KT survived with 25% of his health in the clip too and if B4 which that guy had would hit it once it would surely die in that assalut. You see the clip as one dimensional battle but the truth is Allies don't have direct counter but still have enough indirect ones to deal with KT. That being B4, mines, IS-2, Tag vehicle, Jacksons(due recent buffs), fast medium tanks, at nades. When you used your abilities right you could destroy KT even before this Armor nerf. Or when you were good enough you saw the fact enemy is going for it and you never let them get to that stage. I was never fan of handholding and I never will it seems like cheap way how to give unskiled players (missing of timings, bad earlygame to midgame play while your faction is great at these stages, lack of knowledge how to face heavy tanks with your units) unfair way to beat ones that went for high risk high reward tactic and managed to pull it off.
