As per Cider's request this is my current block value gear. After all buffs/equations it puts me at 823 block value before trinket and 1052 after trinket.
There are more pieces in the T5 instances like the T5 gloves/pants that would add quite a bit more block value to the set.
54 T4 Head (ZG enchant)
29 Steam Hinge Neck
32 T5 Shoulders
38 Farstrider Defender Cloak
45 T4 Chest
33 Vambraces of Courage
38 Iron Gaunts of Maiden
29 Sha'tari Vindicator Belt
0 T4 Legs (not legs with block value)
30 Red Havoc Boots
39 Seventh Ring of the tiristfallen
24 Dath'Remar's Ring of Defense
51 Shield of Impenetrable Darkness (block value enchant)
plus my strength (276 and i have no idea how that translates) as well as shield mastery
