Ruinit,
Thanks for the log and feedback.
tbh I don't see any issues with the spells being cast. I see it used flash heal but only when the target was below 50%..there are settings in the GUI for this maybe increase those if you want to see more heal and flash heal usage. You could also try turning off Damage that will increase the usage of said ability's.
I am going to paste your cleaned up log here, maybe one of my testers can elaborate more. You can of course tune Oracle to pretty much do whatever you like by playing with the settings. I encourage people to post there settings to the forum so others may benefit.

Thanks man you are awesome! The problem is atonement healing for disc is really the way to go and maybe I don't understand the settings because I don't see any way to set heal, greater heal, renew etc. I will look into setting more just seems to me out of the box as it were, disc and holy pally as well were both healing far better before some changes were made. Maybe a fellow user can share their setting with me to test

Awesome cr though thanks for your continued efforts on all your stuff! Really!
