i dont think that there are a whole lot of options for uninque paladin builds but there are other options with other classes. for example i have made a unique and effective zon by myself. i have also made a good assassin that uses different skills than most.

But generally the most effective builds are popular becuase they are effective. so while both my zon and assassin are good duelers neither one of them can stand up to a cookie cutter V/t if the person knows how to duel with it. and the reason is because V/t's are just very powerful builds that can deal good damage with either of thier skills thus they are very popular.
