actually dont, moira is the only support who can heal more than 30hps in 2 diffrent places, or like put a heal on a spot and go to damage and vice versa
i think the other two who can do both are brig who needs to constantly do damage to inspire and to do damage she need to be melee range, and bap can do both but in the same LoS
i think the only think she is better than bap is her survivality, she is like the better sup to survival a dive alone
