The jack of all trades but master of none. I would rather have a true impact than one that can barely be seen even by the Mercy herself. I have already suggested that one way to make Mercy feel better is to allow her to toggle between the branching beams and a single-target beam that gives her improved healing (120-200 hp/s), because currently the ult isn’t fun and she needs to be able to deal with focus fire. Even Moira without her ult can burst heal her team better than Mercy can in Valkyrie.
