It's bloated not indecisive, in my opinion. Just a lot of mandatory talents, and it doesn't help that one of our mandatory talents requires 7 points in another tree.
One of the things people overlook is that Smite is not a method of healing unto itself outside of very rare scenarios. It's utility - Smite to top people off during low periods, or even better, Smite during lulls in raid damage then enjoy your +15% healing for the heavy stuff. A/A is in no way contradicting the general flow of the tree.
I also think Chakra is a very clunky mechanic, although they've trivialized the downsides with the new longer duration. Originally it was a fairly complicated and totally unnecessary hoop to jump through if you wanted to be an effective healer, now it's basically a "hey press this button every minute and you're good to go" button. Not elegant at all, IMO.
Hmmm my post is starting to sound like QQ. Overall I'm happy with my toon, I just think there are a lot of flaws in the design that I would like to see improved. And unfortunately, I have no good ideas on how to improve them.
