Primary fires did
Did 90/135 (Ashe)
And 85/127.5 (Cassidy)
This would buff body shots TTK when a target his being healed but also need headshot TTK when target is being healed while ALSO addressing the massive over spike of accuracy since season 9 without bothering either hero, but also opening up more methods of saving allies than extreme burst healing.
The only drawback is the skill gap closure (would be mild to moderate) by reducing the reward of high accuracy.
I counter this philosophically by saying the season 9 changes threw that away in the first place and that headshots are way too forgiving with hitscan now to deserve a 2.0 multiplier and incontestable usefulness against non hitscan.
