Things Mercy can do:
- low burst, sustained healing: requires teammates to avoid critical damage
- resurrection: requires teammates to cover her during that time
- damage boost: requires teammates to be accurate in their attack
- guardian angel: requires teammates to practice social distancing
- pistol: requires teammates to avoid damage since she isn’t healing
Things Mercy cannot do:
- burst healing: she can’t undo damage fast enough to save a teammate from burst damage
- offense: she can’t help kill the enemy before her teammate dies to burst damage
- utility: she has no emergency cooldowns to pause enemy burst damage
If Mercy’s teammates play defensively, she works really well and is fun to play. But because this game is a high-burst bloodbath, everyone is chasing kills instead of defending themselves. So the Support role needs to help in that regard with burst healing, extra offense or utility cooldowns. Every other Support has some or all of those things, while Mercy has none. This is why she is so team reliant, and since everyone is chasing kills, it’s why she suffers.
