You are fundamentally misunderstanding the point of Dissipation. Dissipation is not supposed to be used in 99% of the fights you encounter. Dissipation is basically the SCH's hail-mary/onside kick at the end of an (american) football game. It is the bright red button on your control panel with a glass box over it that says "DO NOT PUSH".

When everything has gone to hell and you need to survive that last 5% and have no MP and are out of aetherflows, that is the situation Dissipation is for.

It is supposed to have a huge penalty for sustained healing, because that isn't when the ability is supposed to be used.
