The studio said that player feedback and an internal review prompted the healing change recall, although it hopes it will be able to bring the full vision of such changes in a future patch after more testing.
“The goal of this update was to increase the burst healing of healers while simultaneously balancing healing per second (HPS) values, and resource management for healers,” BioWare said. “We are not completely satisfied with the present state of the healing changes, and want to give the community more time to play with the changes and offer their feedback.”
