I think you got mixed up there. As a BLM downtime for you would be the bits where you need to move and you can't do your primary job (dps).
For a Healer in a decently competent group, the only time they have to do their job (aka healing) is after raidwides. Esp. As overhealing does nothing to help the group defeat the Boss.

To try and paint you a picture of how healing downtime feels, imagine as a BLM a fight where you die if you stand still outside a handfull specific mechanics that last 1-3 GCDs. That's how much healing is usefull in EX trials and a lot of savage.
Sticking with the above example also might help illustrate the other part of the issue. Afaik, outside Triple Cast BLM has like 1 or 2 instant casts you'd be expected to spamm all of that hypothetical'we hate castbars fight'. That's about what healers have as well. A DoT a spell and some once a minute extra options. And outside AST with the card system, there's really nothing to any of that beyond sastasha level'watch the cast bar fill up again and again' casting mechanics. None of it interacts with each other, nor the Healing part of the kit.
