Not if i have a choice, i think dismemberment is downright gross. If it's only optional i won't have a problem, but if it's not or imperative to the melee class- i'll be rage/ranting about it on the forum and waiting for a mod.
Definitely, unless it's like the Bloody Mess perk in FO. Like if i hit someone in the arm and their head comes off, then no i will not get it. Decapitations add more realism though, so YES. :D
Unless it gives me something more than decapitation. The perks are thin enough as it is.
im sure it will be like fallout with the extreme gore perk forgot name but it gave extra damage and a chance the person would turn to a pile of mush and yes i will
