ok, so there isnt a warlock officer/class leader atm, so ill have this here for you and update it till we have someone.
Some of this gear may not be available atm, but its a good base so kinda help you on your way. I dont always agree 100% on guides, i usually do my own thing, That said, for locks i went sp/hit(8ish%)/creit/stam. int is nice but i prefered stam to help stay alive on certain bosses and to lifetap and it not hurt too much. But to each their own as long as you perform well!!
