I had a lot of work to do, wasn't here for a while.
In my opinion sneaker build could work this way:
10,1,10,1,6,7,6 or 10,1,10,8,3,6,3
Bruiser/Heavy Handed
I don't believe HtH needs a PE, especialy sneaker one, just for earlier mentioned crit. PE. Charisma version is not for solo actions, so count with it.
BRoF seriously works on melee? It should be only for ranged weapons, shouldn't it?.. Quick Recovery, Toughness, Watchtower, Bloodthirst, Silent Hill Death, Nerves of Steel, Lifegiver, and two other perks to choose from .. for example Dr. Strangelover/Psychopath/Adrenaline Rush..? Dodger is not working I heard.
Unless you will have higher PE, watchtower is useless. Living anatomy is waste of perk too, if you don't have higher crit.chance, and +3% crit.chance will not do much.
First case tag:
HtH,FA,Sneak
Second case tag:
HtH,Sneak,Leadership (you have to team up against prey, no solo actions.)
P.S.: Have you thought about Gifted HtH build?
