this is not RNG this is the average value, can you understand this?
in practical its even worst, because all of this number are taken in close range penetration, in practical most of battles are in long range, the nerf in long range its much more big
do not try to pretend to be a professional player when every time you speak you looks like an ignorant...
Average values are an oversimplification here. Tanks don't fire fast enough for everything to average out.
Take the following scenario: a Jackson starts attacking your Panther at maximum range.
The Jackson has a far penetration value of 220 and a damage per shot of 160 which means it has a 69% chance to penetrate the old Panther and an 85% chance to penetrate the new Panther. The old Panther has 800 HP meaning it takes five penetrating Jackson shells to kill and the new Panther has 960 meaning it takes six penetrating Jackson shells to kill.
Whether or not a shell penetrates is a biased coinflip and therefore you can apply the binomial distribution to it.
This I believe illustrates the difference between the two Panthers more clearly than average values do. The new Panther
will survive five hits from a Jackson no matter what whereas the old one has a 15.4% chance to be destroyed. The new Panther is also slightly more likely to survive an engagement where the Jackson hits it six times. In engagements where a Jackson has time to fire off seven or more shells the old Panther is slightly more likely to survive.
That's not a bad tradeoff: as you'll usually withdraw your Panther once it gets too beat up I'd say the extra survivability in shorter engagements is preferable to the extra survivability in longer ones. There's also lot to be said for the sheer reliability of being
guaranteed to survive an extra hit over the old version.
You see a similar pattern against medium tanks. Here I've replaced the Jackson's weapon values with those of the Panzer IV, a typical medium tank with 120 penetration. The new Panther is
slightly more survivable until you get into much longer engagements.
Where the new Panther falls short is at Veterancy 2.
A +10% armour buff to 260 armour is 286, not the old Panther's value of 320. At Veterancy 2 the new Panther is strictly inferior to the old one.
Overall I'd say this is a net buff to the Panther's survivability. There's undeniable value in the reliability of extra health and the armour reduction only cancels this out in very long engagements.
