I have to apologize. It was not my intention to insult, be dismissive or anything similar. I do appreciate your desire to help me understand and I thank you for it.
To me, personally, the difference between what I see my char doing and what the actual result of my char's actions are, is because of badly implemented combat system. If I see my char hitting something in the back, I expect this to be the actual result in the fight. Not "Oh, while you were hitting him in the back server decided he is actually already turned towards you".
