Backstabbing issue

I would like just to give my feedback on this topic. Honestly after all this time polishing the game i expected the backstab to be perfect. In reality after the latest release i still have issues with it. More than once, with different weapons I was standing right behind him and couldn’t back stab him. You should really try to improve that. In addition I just made a new character and was trying a curved two handed long sword (dont know the name in english because i am playing a foreign version) and more than once i had to get up real close to him to backstab him. Frankly you are perfectionsists and if you have a long weapon you should need to get that close to an npc to backstab him. Thank you and hope you finally solve this issue.
