The title speaks for itself...because i really get [edited]tired taking 3-400+ dmg from arties 2 tiers lower than my well armoured tank...and this damage is at the front of the tank...not rear or sides...

An example with a Tiger I getting hit on its front hull by a M44:

 

nominalDamage = 550

impactDistance = 0

splashRadius = 7

nominalArmorThickness = 100

spallCoefficient = 1

 

r = [0.75, 1.25]

 

= 0.5 * 550r * (1 - (0 / 7)) - 1.1 * 100 * 1

= 0.5 * 550r * (1 - 0) - 1.1 * 100 * 1

= 0.5 * 550r * 1 - 1.1 * 100 * 1

= 0.5 * 550r - 1.1 * 100

= 275r - 110

= 275[0.75, 1.25] - 110

= [206, 344] - 110

= [96, 234]

 

So the min roll is 96 damage while the max roll is 234 damage :)

Also the +/- 25% damage RNG is still factored, so the HE damage can be extremely random.

 

Technically an arty with 900 alpha can hit an E 100 for almost 500 damage, if it hits the hull roof directly and maxroll, instead of doing the typical 150 - 300. Or it might hit your gun or spaced armor and do nothing.

How well armored are we talking about? As HE don't care how effective your armor is, or how much higher tier you are. That and most HT still has top armor, if he hits you there. It won't matter how much lower tier he is.

 

iirc the splash damage is created around a 45 degree cone from the impact point if the HE shell fails to pen. Anything caught in that gets a damage roll based on how thick the armor is etc.

Same if they hit the ground near you. Then it's based on how much if your tank is within the cone it creates. And if it can reach internal modules, or only external modules etc.
