Nature's Focus – Requires 5 points in the Restoration Aoc Gold tree, which gives you a 14% chance per talent point to ignore interruption to your healing touch, regrowth, and tranquility, spells from damage. 5 point limit. This sounds like a nice talent, and in some situations it can be useful, but in general it is not that worthwhile. For one thing, you are soloing you should not have anything hitting you while you are trying to cast heal in PvE and if you are soloing its unlikely the mob is hitting you enough that you need to get heal off incredibly quickly, if you've picked a target of your level. In very high end PvE, if a monster goes off the tank and gets on you you're going to die almost regardless of what you do, so this becomes pointless.
