Add a new ping response that automatically occurs for support players TO team mates when they ping “I need healing!” While they are being healed or have just received healing.
Example, your mercy beam is currently attached to or was JUST attached to them less than 1 or 2 seconds ago and they say “need healing!”, your hero automatically says “you’re already being healed!” Or something like that to them.
Baptist: “I just healed you!”
Mercy: “I AM healing you, get to cover!”
Illari: “you’re already being healed, get out of there already!”
Brig: “already on it, get back!”
Etc etc.
I ALSO think it should play at an audio priority slightly above normal so it’s very clear that you’re misplaying and your support is not made of magic.
