It's so hard to find a decent guide on healing ... not on a templar, so while also excluding the warden for now. I bring you a collection of useful guides on healing on these classes below.



Nightblade healer


There's alot of guides and videos for nightblades, but I found these the best because of detail and content.

Sorcerer healer

I know they are a lot of people who do this class and role, but finding a guide for them was an abyssal. Here's the best I could find.

Dragon Knight Healer

There's actually a lot of good ones here. I picked these because of the diversity and content provided.
