zealot - 3 x holy fire, conviction

if any1 using or tried it, i would like to hear experiences and about the rest of gear options.

I have a

Holy Fire with HoJ and dual Dragon.
What do you want to hear?

is it any good, farming areas, can it do solo ubers without problem, the rest of the gear... things like that

Depending on where do you farm.
Unlike Tesladin, no Grief so the physical damage is very low.
You rely on fire damage.

Area without fire immune (cow, stony tomb,

Icy Cellar).
You can wear full MF gear (chance gloves, war trav and so on) the pulse damage is high enough to 1/2 shot everything.

Area with fire immune.
Chaos run: I don't like it, too many Fire Immune monsters here and curses are everywhere.
Baals run: doable. I skipped all fire immune monsters at the 2 levels of wsk.
Lister and Colenzo are fire immune but it is not a big deal for me.
BTW, I have an Act 5 merc with Grief & Lawbringer. He helped me a lot here.

Uber

Conviction cannot cut the Fire Immu of Venom Lord (and all other immu too if I remembered well).
It take time to find Uber Izual because there are many Venom Lord in

Furnace of Pain.
Uber Diablo too. He spawns a lot of Venom Lord.
=> Doable but you don't want to farm torch with him.
PS: with

Smite without any change on gear nor skill, you will kill uber bosses faster lol.

Gear against fire immune monsters: all I search is CB + OW.
20 IAS + 10 CB gloves, G-face, gore ride, dual leech ring.

tyvm for ur time and help. this is great info
