Pretty decent at it now for AoE. They buffed RJW and SCK a lot but increased its mana cost proportionally, but its efficiency is worse than generating Chi with Surgings, so basically it's our burst tool now. That's how we convert more mana into more healing. The mana cost is 20k (max mana is 160k) but it does about 2500% spellpower compared to surging's 300%.
