There is currently no way to simulate big pulls or situations where the healing is focused on dps or just a weak heal.
Now I’m trying to make my own scripts, but maybe someone already has a private script for this?
Swol has some plan to do a Mythic donjon but it’s on the to do list after the launch of SL.
Alsotheir is " slider" for heal to optimize between dps and hps in the optimizer.
