Though not a powerful Force ability, it would be cool to see onscreen why Force users do not or cannot use the force on their opponents lightsaber, or breathing mask in Vader’s case?
The ability to turn off an opponent’s lightaber off with the Force, or alter the settings on Vader’s chest plate, or anyone else using a breathing mask, would be interesting to see explained.
Maybe some sort of “Force Protect” power is used in combat between the Force users?
