Yeah but some elemental builds are just fun to play with
Paladins can be great fun you build your stats right as well. Vengeance/Conviction is still great. Then spend the rest of your points evenly in the single resists to buff your vengeance.
I personally don't go for the mainstream characters that everyone makes. I choose the strange combos, tho I did make a vengeance/conviction pally... started getting popular as I made it oddly enough. I have a meditation pally in the works. He's fun as i don't need mana steal and can cast B Hammer forever.. but damn the more I play AS him.. the more I want to play ALONGSIDE him.. heh.
Summoning Druids are fun too.. they're tough at later difficulties, but they're still fun.
Also pally's can own in hell because unlike other classes they can still have kick ass Resists in Hell.
