Ethereal upgraded hoz loses defense due to shitty Blizz programming. Non-eth is better.
Use an upgraded non-eth hoz, best smiter shield in the game (though newbs will argue the benefits of Exile's LT in pvp).
Some choices of skill combos are:
Smite/FoH (V/t)
Smite/Charge
Smite/Hammers
Smite/Hammers/FoH (though I don't suggest this to you as I don't think you'd do it right)
Smite/Zeal (though this has lost popularity due to people actually needing AR now and not being able to abuse the Eth bug)
So yeah, 3 choices. You'd probly do best with Smite/Charge. Max your 3 smite skills, max Charge, and then max Vigor. Rest of points in Might, if you have any. You could also put a few in Blessed aim for passive AR bonus, but that's your choice based on equipment and your level you wish to stay at (chance to hit, really).
For a pure smiter, I'd do:
Astreon's (+4/85) Ber'd
Upgraded Hoz Ber'd
15% verdungos
Bloodfists
Enigma Archon/Dusk
Spurs, most likely (East duped rare, any boot with good run/walk, resists, +stats is great. Do NOT pick gorefoot as it's +vigor does NOT help you)
Raven / BK Ring
Harlequin Crest Ber'd
Mara's or a beastly +2 pala/+life/+run-walk/lifeleech/resists (or stats) ammy
On switch:
+6 CTA / Sigon's (for style)
Anni
10 combat GC's with +life
9 SC's with resist, run/walk, life, fhr (anything you need, like 1 fhr to hit the next breakpoint, whatever)
That would put you at a 47 Holyshield/31 Fanat/47 smite with CTA casted, skills in order of importance.
Keep your dex as low as possible to keep 75% blocking (shown with a mouse hover-over on the char stats screen [defense rating part] with holy shield casted) and strength just enough to wear all your ****, check by doing weapon switch. Do not use an elite CTA, as that's ****ing stupid and will make you possibly unable to pick up your corpse.
