I realize that you folks are still working on the Reaction system, likely why Shield has been removed from the game( hopefully temporarily ), but changing Feather Fall from a reaction to a bonus action takes away one of it's main uses: protection against surprise falls.
Under its current implementation if a Wizard were crossing a bridge of webs and the bridge gave way a Wizard would have no way to mitigate the damage and would likely fall to their death.
This could be a temporary thing as you folks are still hammering out how you want to implement reactions but I would request Feather Fall be changed to a reaction so my Wizard can get over their fear of high places.
