When holding a melee weapon like a sword i want to be able to kill enemies with the weapon while performing a stealth kill.
my character shouldn't just twist the enemies neck or do smth like that when he is holding a sword, thats just stupid.

Loved stealth kills whilst playing a Malkavian in The Masquerade Bloodlines.

Agreed but every gameplay mechanic in this game is half-baked or broken. I still like it though when I have ~30 mods installed fixing or improving things. Except today when I can't play the damn thing because the update happened.
