This list totals out at 1797 Hit after reforging all secondary stats to Spirit/Hit, so obviously reforging every item won't be necessary. Don't forget your 55 spirit from the leg enchant as well!
I hope you find this helpful and please play around with it! I want feedback and in no way saying this is the "final" BiS list for normal mode 4.3 loot.
