well i hope they at least make silent death work without sneaking, but if you attack from back.... taht would be nice, becouse well.. if a gun guy runs from you - hes back at you, and you chase... you get him while he's waiting for his snipe shot with a back turned your way... and kABAAAAAM hes dead, that would teach them to not run away and still make chasing meelee guy deadly, hell make it have solid sneak req just for the sake of it, but i very well hope that silent death will work
