The hidden options to make heroes even better was really solid to listen to.
Lucio: option to hold shift to go to speed move instead of shift as a toggle in case you forget to go back to heal.
Soldier 76 and zarya: always show health of allies to heal them better
Mercy: has a toggle heal instead of hold
Reinhardt: there's a toggle instread of let go for shield but not a good option.
Widowmaker: toggle zoom instead of hold down to zoom, and a change sensitivity for zoom mouse sensitivity
Genji, Hanzo, Junkrat: can change it to auto run up wall when jumping near wall instead of holding down space to go up the wall
