Sure! I'll add a detailed section to the guide on this later. Its all about counterbalancing the amount of incoming damage to make healing somewhat predictable for the healers. If there is no expected incoming damage, things like Foresight, Bloodbath, and Dark Dance are great to use in order to maintain mitigation and counter balance damage by self healing. Parrying will also proc Reprisal which is a nice -10% outgoing damage across the board while Souleater is a frequent 400 potency self heal. Your percentage based cooldowns should be used for big spikes in damage or if the healers need to turn their focus to other people for healing. In Alex Floor 1 for example, the first half of the fight there is only 1 enemy, so you should able to be get away with minimal cooldowns. Then, as more healing is needed, you can gradually use more cooldowns so the healers don't have to pay as much attention as they did to you before.
