This a viable pally pvp build...?

I saw a guy using this and he owned everyone 3vs1. No one could hit him and when they did it didn't do too much. But every time I say something about it to a friend they say that a V/t is much better. Anyways;

20 smite
20 fanat
20 holy shield
20 defiance

helm; 2 ber coa
armor; enigma
weapon; doom
shield; exile
belt; verdungo
boots; goreriders
gloves; draculs grasp
ammy; maras
rings; raven/bk or bk/bk

so he had maxed fanat aura going, lvl 16 defiance, holy freeze, then maxed holy shield+maxed defiance as synergy=lots of defence.

maxed resist and dr

anyways, he owned everything in site.... but didnt see a good V/t come in so i dunno...

is it a viable build? (this is ladder by the way)
