Yes, a little too focused perhaps. Use a slayer who fights two weapon style.
Needs two weapons, high crit range (15+), and the following feats:
Relentless Butcher, Dastardly Finish, and merciless butchery.
Open up with a close range death attack (cleric) and kill/maim the survivors in melee.
My favorite setup was the beggar on the corner asking for coin. Cleric donates and gets death attack/sneak attack/possible butchery in return. Outside store workers join in as "associates" of the slayer.
