But, the game didn't decide for you. The game calculated that the hit would have landed, despite your attempt to evade or block or whatever, and that it would kill you.
Yes it did. How can the game 'calculate' if I'll successfully dodge an attack or not? It merely looks at my health, sees that the chief's power attack deals greater damage and straight up runs the kill animation. That's the game deciding for me. That's my control in combat being removed. Often it occurs when there's as much as a meter distance between us as well.
You don't evade every blow. You don't block every blow. As evidenced by the fact that your health was not full. Since you CAN get hit, what's wrong with the fact that you got hit?
Because it feels unfair. If I die because I got hit in combat, that's fine. If the game decides for me that I will get hit in combat where I might feel otherwise, and runs a death sequence over which I have no control, it's effectively ending a fight which I might have won had I been left to my own devices by removing my control and having me die a cheap, automatic death.
I feel strongly about this. It's a terrible addition to combat, in my opinion. Very restrictive. With dragons I can almost understand, given the grandiose nature of the enemy in question, but with Orc bandit chiefs, I can't stand it. (You try avoiding putting points into health and fighting a bandit chief. It hampers combat and punishes my playstyle. I have a right to complain.)
Edit: I hope people don't think I'm a crazy hack'n'slash warrior who doesn't pay any attention. I'm a very careful, light-armoured fighter, with block as my main skill. I use shield bashing as my principal method of opening up the enemy's defenses and countering power attacks (seeing as there's no dodge). Because of the emphasis on bashing, I add a lot into stamina and neglect health somewhat, because I don't need to grind it up where I can block and dodge my attacks. With this playstyle emphasing block, on earlier levels where you still get damaged a fair amount when you block (due to lack of perks), blocking will grind your health down and eventually the animation will begin running. It's a pretty frustrating problem; it discourages my careful sword'n'board playstyle.
