WHM Healing Spreadsheet

[Syncness]

For whm,
Crit = overheal. You can't wait for tank hp to go low and hope for crit cure I to top off your tank instead of casting cure II.
Crit heal on 1st cast right after pull = dead whm.

You should be using Swiftcast > Stoneskin > Regen/Cure > Cure/Regen on the pull. This is more than enough GCDs for tank to get aggro.
