It's worth noting that good healers will take the opportunity to set themselves up to be able to blow GCDs on DPS to assist the party effort.

SCHs aren't noted for contributing as off-DPS for nothing; it's a combination of shielding, a micromanageable healing pet, and Lustrate up their sleeves that make stance transitions particularly smooth and safe for them. WHMs can certainly create windows for themselves to contribute DPS in a similar way, but they have to be more careful about it because of how greatly the GCD impacts the flow of their gameplay.

And yes, most content in the game, including end-game, follows a script and has few variables. At end-game, your variables are basically limited to things like T6's Devour or T7's Voice/Shriek mechanics, where you know what is coming and when (and even which roles or enmity levels can be hit), but not necessarily which individual player will be affected each time.
