I don't actually understand, Lealla, why you would put 5 points into Naturalist (Reduces HT cast time by .5s)...
Currently, I never cast HT unless it's combined with Nature's Swiftness. Furthermore, you aren't taking Nature's Grace to reduce the cast time given a RG or Nourish crit (though NG works with any spell crit), and you're not glyphing it.
There was a debate between the healing throughput of Glyphed RG vs. Glyphed HT, where Glyphed HT worked kinda like a flash heal (that priests have), and Glyphed RG won hands down. While this MIGHT not be relevant with Imp. RG reduction, I still wouldn't waste five talent points on a spell that's not going to be cast all that often without NS anyway. If you want a big-ish heal, Nourish is that spell now.
Personally, on my resto druid, I used those 5 points and put them into Improved Tranq (for the times that I use 'em... not often, but I like to have it on CD just in case), and Subtlety, because well, I'm an aggro whore.
