Sage has got the 1 heal every 40sec or whatever and a rez for ult. They have started to make her more expensive to play with her ability buys.
If they make another healer with the potential to heal more than sage they should make playing the agent very expersive.
Something like you can have 3 heal charges... But they cost 500 a piece.
This way the hero is powerful but the person playing the hero will have to constantly use eco weapons... Which would create a disadvantage in 1v1s... Or the team would have to buy the weapons for the agent.
Could be a cool playstyle if you have a healer that is putting up value but also nasty with something like a Marshall.
