My guild just downed Heroic Twins and are about to start attempts on Anub. For the strategies we saw the off-tanks need 103% total avoidance (while shield blocks are up) and >3000 Block Value.
Ignoring item levels, does anyone have a list or know where to find one of the best in slot gear to reach these values for both a paladin and warrior?
You only need 101.6% combined dodge/parry/block/miss after raid buffs. As for block value, it depends how many offtanks you're using. You probably would want close to 3k if you're solo offtanking the adds. However we use 2 add tanks and I've done it fine with me and another warrior around 2100 SBV.
