I recently got my Deathbringer's Will (after losing it to three ret pallies over the past two months, but that is another story) and exceeded 780 armor penetration. I know the first thing to do is to change all my red slots from agility to armor penetration, which I have done.
However, that being said, I am not certain what to do about yellow sockets. I was previously using Deadly Ametrine. Do I keep these to at least have some agility bonus, or switch them to an armor penetration split gem? Also, if I do switch to an armor penetration split gem, what is the best one to use? I would assume ArP and crit.
Any information would be greatly appreciated. Thank you in advance.
