Well here’s an example of how the mechanics could be entirely different, without changing much.
Mercy
Sympathy Bond:
- Mercy blocks half of incoming damage on a teammate, and receives half the incoming damage to herself.
- Bonded teammate has a halo visual effect above them.
- Casting the ability on the same teammate twice cancels this ability
Resurrection:
- Default keybinding to Q during Valkyrie.
- Resurrects one fallen teammate, this teammate is restored to full health.
- Zero cast time.
- Resurrected Teammate cannot take any action for 1.75 seconds, and glows bright yellow.
- If this teammate dies within 4.75 seconds after being resurrected, they are put on their former respawn timer.
- Healing, Zarya Shield Bubbles, etc are effective on the resurrected teammate.
- Ten second cooldown during Valkyrie
