Patch 3.0.2 changed Nature's Blessing from 10/20/30% Bonus Healing to 5/10/15% Spell Power in keeping with the unification of spell damage/healing.
The TTT has it different, and (I think) correct:
1) Ancestral Knowledge (AK) now affects Intellect so each point of Intellect is really 1.1
2) Shaman now have talents that boost crits or proc on crits
3) Nature's Blessing converts up to 15% of your Intellect into Spellpower
4) Mana restored from Mana Tide is based on your maximum mana
5) Replenishment is based on your maximum mana
10 Intellect = 6 mp5 if you have a 5-minute fight with Mana Tide and 100% uptime from Replenishment.
10 Intellect also gives 3.3 crit rating and 1.8 spell power

So, (100 Int * (10% From BoK + 10% from Ancestral Knowledge)) * 15% conversion rate from Nature's Blessing = 18 SP
