Well, the "best" thing to do in my opinion is to be a Jewelcrafter. +70 pen to cloak, one +84 JC gem and one +50 gem. Then all the rest of your gem slots are +strength and you reforge all that shitty expertise and crit until you get the +hit cap.

I have heard and I believe I read somewhere that currently it's even better to ignore +10str gem slot bonuses in favor of the pure +str gems rather than use the hybrid gems--IE, 30 strength and 20 haste/hit/crit is worth less DPS than 40str in EVERY case. I can't find the post I saw that at though, so take it with a grain of salt.
