Have you maybe considered that Dissipation is, in fact, not supposed to be an "oh shit" button first and foremost? Yes, its usage is situational, but so is the entire SCH kit. Scholars are tactical off-healers, not just lore-wise, but in the way the entire toolkit is designed. Every single skill, except for Broil, which we got in HW adds to this, and Dissipation is no exception. It's a wonderful ability that has much strategic value and should be used by every good SCH. While I do agree that the healing increase should affect Lustrate and Indom, I feel this is less of an issue with the skill itself than it is an oversight in the general way that spells, abilities, and healing buffs interact.
