OK after a few reboots it's working for some classes but some don't have the boosts. I didn't change anything, just pulled up a few different classes to test them.
Nec / SK works (boosted damage, boosted heals) Mage, Paladin, and Shaman do not. I didn't finish testing the rest yet.
update to above: You're right, it's a cast time formula. I just found all that and will adjust as I need to scale. You're awesome! Thank you!
Edit to add where I found it for anyone else wondering.
