I agree with everything Nayh posted.
You should focus on high base AP and HP stats on your equipments and compound AP on whatever's AP compoundable. Get an Inferno set and a boss weapon (Queen, Soki or Spicy) comped with attribute for max damage.
Going pure HP could help your survivability, but since you're already AP, that's fine too. (Also being pure AP buffs more AP for you in Evo, so that's good.)
I do believe having some kind of HV/AP weapon (Altiverse) would help you a lot if you combine it with a Guardian that knows Shield Breaker to kill bosses easy.
Good luck with what ever you choose to do :3
