I feel like the shield is due for a rework. How i think it could be changed is instead of having 4 little balls float around you, have 4 quarters of a circle floating around you. That way you're actually protected from a bullet instead of you dodging a shot but your shield gets hit and is removed, not fair on the player. The shield should regen one quarter only if the play does not get hit during the room. That way players who dodge shots are rewarded and players cannot just hide behind the shield constantly.
