You have to include Tier tokens as boss drop gear....and according to wowhead, all FIVE tier pieces have spirit on them for healers. Not to mention the ring and neck and OH that are all spirit haste. If you think Blizzard is failing Holy Priests, you are very mistaken.
On another note, on the PTR, Mor'chok was dropping tier tokens in 10 man normal. It's not listed here. Was that a glitch, or just a miss by MMO?
