This is quite a safe build that allows Anduin to stay on the back line. That is especially helpful if you need to pull someone with leap of faith. If you are in the middle of a fight, it doesn't help. Make sure your allies don't dive to deep into the enemy team, otherwise you will be punished when trying to save/pull them.

There is the option of going "Binding Heal" at Lvl 7, which heals Anduin everytime he uses Flash Heal on an ally and than at Lvl 16 going for "Evenhanded Blessings" which reduces the cooldown if another ally than the previous one is healed with Flash Heal. I do that sometimes, when I feel quite save.
But "Blessed Recovery" is okay most of the time!

I usually go for Lightbomb, because Holy Word: Salvation is so easily interrupted! Make sure not to wait for a big fight. If you can secure a kill, use it!

"Glyph of Faith" gives you a second charge of Leap of Faith which can be pure gold in endgame, when the death timer is very long.
