Revert the change. The new Harsh Discipline is awful being connected to Radiance. The old one played really well and was one of the main points Disci was fun (e.g. turret Penance).
Also maybe think about making Disc a bit less smite spammy cause its boring. Im sure as a game developer you can bring yourself over and design something fun than spamming 1 button forever since its your job.
Old harsh Discipline did feel really good to build and store. Don’t really like the proc from radiance with the 10.2 changes. Feels like you have to drain your mana now for it or only use it after radiance for a burst of atonement healing. It had more flexibility before.
