The new top of the resto tree for druids is a spell that has a 15 second cool down Swiftmend. I found this below. But basically it works out that you have a 1100 hp instant heal every 15seconds, on top of Natureswiftness and the rest of the druid heals.

Swiftmend 
254 Mana, 40 yard range 
Instant Cast, 15 second cooldown 
Consumes a Rejuvenation or Regrowth effect on a friendly target to instantly heal them an amount equal to 12 sec. of Rejuvenation or 15 seconds of Regrowth

According to people who tested it at E3, it does not take into account +heal gear which is disappointing. It should still heal for around 1100 (if you have GoN and Imp rejuv), and maybe they'll change it before release.

But of course the most important part about all of this is the fact that feral druids can now return the favor to healers by dropping an Innervate on them. Can you say Holy Nova ftw?
