Well in my opinion it would be pretty much whatever works, I dont think there is a "guideline" to a build like this there are many possibilities. But yeah I would aim for IAS,Max Block, the basic necessities for a good tank.
As for gear I guess Grief, or BOTD?
As for gear I would go for FORT, dont see anything else that would be right? but then again I may be wrong.
Shield Im thinking Exile would be awesome? or HOZ, up to you? Oh you can get a 45 res shield and make a spirit..?
Helm?.... Ehh COA/Shako?
I think for rings and amulet Angelic combo would be awesome? but then again if your going for max block wouldnt that be enough already? so I dunno gamble with this one?
Boots options are Gores Treks Waters? I think thats about it?
Belt?... Ahh shit forgot the belts on diablo sorry buddy haven't played in a while

Gloves... Same as above.
If your going to use Vengence I would max the synergies, and probably ( that green Aura that does -res to enemies lol,) since your dmg will mostly be elemental?
Test with Hero Editor.
also I may be completely talking out of my ass, I haven't done D2 in ages.
