No, not deep into blood. They are deep enough to get bloodworms 3/3 and Blood aura 2/2. The rest is a touch in frost and the rest in unholy. Look up my armory and you will see. Bløødfiend (alt 0248 for the special O's) has the highest defense right now, but I am working on getting the others up to date as well. I finally got them all the tanking ring from Azjol-Nerub (final boss). Now will work on getting them the quested ring from Drak'Tharon Keep (http://www.wowhead.com/?item=39650). With these two rings, I can free up some other items to get the attack back up.
