As for the Elefant nerfs, I don't know man, it feels like it won't fulfill its intended role anymore. The damage is nerfed and its pop cap is increased. There is no price reduction or slight increased rate of fire or slight increased accuracy to compensate? The thing is bloody expensive and now it is less effective vs mediums as you intended, but also vs the heavies it is supposed to fight. The increased pop cap will hamper you from getting more units to support it too.
If you do the math, it actually takes the same amount of shots to kill all tanks other than mediums with 640hp. Even the Churchill still only takes 5 shots to kill. However, you never really do 1v1 these tanks anyways so it's still a big nerf to the elephant which I really don't think deserved it.
