The new Mercy rework will provide us with a brand new ultimate, 'Valkyrie'. This ultimate allows Mercy to fly around freely and boosts her abilities.

The Overwatch community has seen Blizzard's attention to detail, and believes that it could be incorporated here. Mercy's 'Witch' skin features her staff re-skinned as a broom, because witches ride brooms. We would love it for Mercy to be able to ride this broom during her new ultimate (whilst using her Caduceus Blaster), to simulate a witch riding on a broom.

Blizzard has been known to listen to fan suggestions in the past, and the Overwatch community believes that this simple quality of life change for Witch Mercy would make all the difference. It would also look cool.
