I loved the staff skills, they were very unique to me. Although, I do agree they need more tweaking, but seems like it could be a promising heal spec for the Guardian class. At least to me, given the ranged nature of it. Basically how I saw it, is that the class became a sort of armored healer with the staff. I managed to find a staff that did good damage but increased my healing. But it was something to get used to. The weapon swap feature is great for this very reason, however!
