Rabenstein
Recruit

I'm not an expert in this game, but I've played it for quite a bit and became effcient. Yet, there are things I don't understand.
Say you have the opportunity to attack an archer from behind, he doesn't know you are there. You are wielding a high tier 2h weapon, for example the great long axe. You chamber your overhead swing for 1-2 seconds and hit him from behind, aiming high. Sometimes he survives - why? I can't see how this is possible since people keep one-hitting me while wearing heavy armor (say +40 head/torso) with side swings from 2h weapons or hack down 2/3 of my health bar with a 1h swing.
I realize there are many factors in damage, like hitboxes, speed bonus, "sweet spot", damage types and so on, but this can't be explained by it.
So, are there additional random elements in combat, for example is the base damage of a hit not 45s, but 30-60s?
