The problem with these builds is that, 1. you dont get force surge which is fairly important in raids when you need a way to sustain your force, and 2. You are losing the chance to use one of your best heals in the game. If you are truly trying to be a healer I don't see how the benefits you gain from your builds outweigh the benefits of going down the corruption until you at least get the last heal.
If your going for something more PVP oriented I can possibly see your builds merits.
This in my opinion is the best out and out healer build. It provides for the most sustainability and allows you to spam a lot more heals than you normally would be able to.
