If you have a Chanter, farm Anuhart Gladiator Pauldrons in Dark Poeta. Those and some Sorc Pieces sell very nicely. Also, the rings Noah's Tears...
This is my rotation for PvP... Soul Strike > Mountain Crash > Soul Crush > Hallowed Strike > Infernal Blaze > Meteor Strike Chain > Hallowed...
I do notice a difference in survivability. And not much of a difference in the amount of times I crit. Very useful for a Chanter~
