Wow guys, I've been away for a few days (moved into my new apartment and haven't got internet yet) and this has broken out into a full out war! Keep it going!
Anyway, on the Smiter topic. Some arguements: HoZ vs Exile
Why people mainly use Exile is for 1) Life Tap 2) Defence
Life Tap is BM, so I refuse to consider it as an option, because I only duel GM, and if you ever get into private dueling you'll learn to respect such things (especially since no decent dueler will duel you if you Life Tap.
More defense = possibly if you are into dueling a lot of barbs, you do get a huge advantage in that sense (and in that case you should fill your inv with +20 life +3x defense SCs, they also boost your defense massively). If you mostly duel other chars, then go for either max Resist Lightning or Resist Fire. The +10 max resi is more effective than you'd think.
On the other hand, upped HoZ has less defense, but more damage (+2 pala and +2 PC), it also has other amazing mods such as +STR, +VIT and +%blocking, as well as a free socket. This means that you can make a full VIT build (no points in DEX). You sacrifice a little defense for more life and an extra socket.
Helm: CoA, Shako, etc. This is really up to you. I like using CoA mainly because of the FHR%. Your Smiter absolutely must reach 86%FHR and CoA goes a long way in helping for that. DR% is needed vs Bowzons, barbs, Druids and other Smiters. Use your 2 sockets as you please, but I would definately recommend using 2xBer. If you duel mainly non-physical casters, use Jah Jah. Some people like using Shako for the +life and +mana, but I don't like it. Namely, the +life on it is nominal, since it is not multiplied by BO, therefore even one Jah in CoA would give more life than Shako. I never found mana a problem on my Smiters, so I would definately go for CoA.
Amu: Mara is a nice option for +skills, +little stats, +resi, but it really depends on what gloves you are using. Some people like to use Dracul's, but once again I hate those because of Life Tap. I would go for +20%IAS +20 STR +15DEX +resi gloves. If you want to have a little fun BMing, use Cleglaws and Highlord, the slow on Cleglaws works miracles against barbs and other melee chars (combine with Arach for enhanced effect

)
Weapon: Grief BA > Grief PB. Range = all in PvP.
Armor: Forti for resis and more damage, but Enigma for FRW%, +STR (essential if using CoA), +skills, +life%, etc. I would use Enigma because I like using CoA. If you want to use Forti, go for Shako instead. I don't recommend using the Teleport on Enigma, since with this gear, your FCR% will be hopeless. Charging around and desynching is way more effective.
Rings: +20 STR +15 DEX +resi +life +mana. Alternatively, you could use an absorb ring, i.e. Raven, Dwarf or Wisp. Just stick to one. 2 (of the same element) is BM.
Belt: Verdungo or Arach. Arach is you want to BM a little, but apart from that, Verdungo is way better because of +VIT (huge life with BO) and DR%.
Boots: Gores are an option, but if you looked at my build, you'd see that it seriouslly lacked FHR, meaning more FHR from charms = less life, so I like Shadow Dancers. +25 stats is awesome, and the 30%FHR is really secksi in trying to achieve the 86%FHR breakpoint. The mods on Goreriders are marginal, because most chars will only take very few hits before they die.
Off-weapon ed% does work with Smite. Ed% jewels, Forti, etc everything works. Check out how damage is calculated in Diablo.
Skills: 20 Smite, Fana, Holy Shield. Rest is up to you, if you like dueling barbs, go for Defiance, if you use Charge a lot, go for that, or if you duel a lot of sorcs, go for Lightning of Fire resi. To be honest, you don't even need Holy Shield all that much, just ensure that you get at least lvl 14 with all your gear on for max chance to block. In PvP, safety > damage.
Daddy_XL = there are actually some Smiters that use Pheonix, but I don't recommend it. Zaka > Pheonix. Also, Steelrends are crappy. Stat gloves are way better. And some Smiters do use Forti, as discussed above.
FeNiXSuNfIrE = if you can kill anyone with one-two Charges then they should delete + remake.
