Consistency of 120 sustained dps. Ana can currently heal for 112hps with her grenade excluding other healers. She alone turns that 120dps into 8dps. Moira can do 155hps with her orb and spray or 215hps with her orb and ult.
Consistency doesn’t mean much if the damage is both low and sustained. 120 damage burst is fine, but as sustained it is basically nothing to the current healthpools and healing values in the game.
