vitality is great, is your item socketed with proper lightning resist gear?

try stacking atleast 250% lightning resist

whats your hp 1500? if you get 10x combat with nice 30+life you can get over 2k hp without too many problems

20 hp/lightning resist are very helpful when dueling other paladins

silence bezerker axe might work better if you can get 6fps smite with it

(silence military pick works good to)

might want to try getting an amulet similar to havok clasp

some rare/craft with stat/life/resist/pal skill is what you are looking for

thundergods vigor works better, maybe ber shako?
