By the way, on Blendassins (Blade Fury Assassins): Probably the best set up for them, weapon wise, is a one handed 6 socket weapon with Nef-Ber-Ber-Ber-Ber-Eth, if you can afford that, and then get the remaining 20% crushing blow on other gear (Goblin Toe? Gore Riders?). The Nef keeps enemies at bay while Eth makes sure you can actually hit. This way you can use a nice high resist shield (I'm a fan of upped Wards with an Um socket). Every shot takes out IIRC 1/16th of enemy life, making it easy to kill bosses even in hell. Also, make sure you've got a maxed Shadow Master and a decent Death Sentry... kill one or two enemies, then blow up the rest.
