hello guys i've recently picked up my old warlock again and i had some questions about gear and gems.
First of all what do i fill blue gems up with? i heard it's best to put in +12 spellpower and +12(?) spell penetration
but i'm not sure what spell penetration does for me i dont intend on doing arena just battlegrounds and world PvP.
What should a destruction warlock focus on in gear? go pure haste or stack up on crit? Thanks for the help i
appreciate it.
