In regards to panther/tiger..... you've heard of hellcat?
Hellcat is a bit of a tough sell. I don't think that I've been giving it enough credit, but also I do think that it's overshadowed by the sherman 76.
I must have had some personal bias going on on my first attempt using the hellcat, it seemingly did 80 damage or something. On actual testing with me looking at the actual health removed, I saw it was a much more reasonable amount.
So, the Hellcat does 160 damage on pen, and it seems to have pen good enough to consistently penetrate the tiger frontally.
I also was sleeping on the "First Strike" ability, which actually
DOUBLES* ups the Hellcat's damage to 240, a very reasonable 50% increase to damage.. Were you to be able to have two Hellcats get a First Strike off on a Tiger, they would only need to pen it another 5 times to kill it. 6 shots if you retreated the Hellcats and drove in with Sherman 76es.
The only issue is that they've got trash frontal armor and they have 120hp less. If the tiger shoots an m16 twice, it's only got 120hp left. That's the amount of damage a single panzer 4 will do if it pens you, which it will because the Hellcat's armor is trash. So, it's a very tough unit to use compared to the pretty straightforward Tiger, especially because the Hellcat and Tiger share the same max range.
Hellcat better than I thought, but still it'll struggle against a frontal slugfest with a Tiger. If the Hellcat can't get off a First Strike, then it's going to take 8 shots to kill the Tiger.
*Wrong math. Thanks Vipper.
