In my opinion, if you want to be a full healer, go for full int, 1-3 wisdom and rest in constitution. For a good healer, the Preservation talent line is better than Growth in my opinion, because the movement of the spirits kinda sucks at some aoe spells of 1.2. In the end, the talent line is up to you, I can only present you my personal opinion^^. gl hf with your druid!
