The Eclipse procs specifically can now be managed entirely within a single macro which will take you all the way to one end of the spectrum and then all the way back. So no need to manage anything at all.

As far as the example goes... If you want to apply the technique to something else.

You can target by:
- Slot number (Good for something that applies to every team you have).
- Character Name (Good for something that applies to only this character).
- Action Target Group (Good for something that applies to multiple characters).
- Current Window or Slave Windows (Window: All Without Current).

With multiple toons on the team, I would probably go with an Action Target Group.
Maybe make one with all the Druids in it.
And make another with all of the non-Druids in it.
Then you can use either as the target.

For the proc in particular...
We have two different mapped keys, which are both called by the spammed key.
One is on, and one is off.
And then a toggle which activates one, deactivates the other, and on the next step does the reverse.
The toggle can apply to one character only, as per the example in the guide... with a toggle per character to individually manage the ability.
But you could have the toggle apply to an entire group (Action Target Group) instead... maybe having Healers who have both a DPS mapped key and a Heal mapped key within the spam key that the entire team spams, and a toggle to switch between them for Healing or DPS mode.
