Well here are the 8 i'm going to make for my special Paladin account, just tell me what attracts you the most and i'll give you the info you need.
Hammerdin> A caster Paladin who uses Blessed Hammer to kill, you know, those little hammers that spin around you.
Zealot> A melee Paladin who uses Zeal as their main attack, simply a 5 hit attack, it's the most common build for a Paladin.
Smiter (defiance)> A Paladin who uses their Shield to kill
Charger> Uses charge to skill, this is not very recommended considering it's hard to use on PvM, but it's nice for PvP. The charge skill is that skill where you run really hard at it's opponent and then hit really hard.

Ranger> Uses a Bow to kill
Conversion/Thorns> The thorns aura returns damage, so if a enemy does 50 damage on you, and your thorns does 500% returned, then he will do 250% damage to himself. Conversion switches a enemy for sometime to your side, the monster will get your aura, and when he gets hitted by others then they both die

Elemental> Using vengeance as your main skill, vengeance does a percentage of elemental damage, with the right skills and all it will do a lot of damage
Tesladin/FoH> A paladin who uses Zeal as their main attack, and Holy Shock as their aura, because holy shock is a synergy for FoH i thought it would be nice to combine those two.
