Resto Talent Builds

I am considering changing my standard raiding spec. Right now, I use 8/0/53, which is a very standard raid build. After looking over some WWS parses though, I'm starting to wonder if the 5 points in Nature's Guardian are really worth it. It procs about once an hour while I'm raiding and it has never saved my life. Hence I am debating the following 8/0/53 build.

Basically, I'm taking those 5 points in Nature's Guardian and putting them in Focused Mind and Improved Reincarnation. I think I will give it a try the next time I respec. It could be that I actually miss Nature's Guardian, or I don't notice a difference with Focused Mind. Only testing will answer that question.
