To start up front, I don’t know how this would affect an older vive controller. If there are issues with that, then a toggle would be suitable.
What I’m suggesting is for controllers that have a joystick, which you normally can teleport with by either clicking in the joystick or pressing your “a”(or equivalent) button, to still allow us to click in the joystick to teleport while a wand is held (and other weapons too, if they suffer the same effect).
With lend-a-hand, you can only teleport with your offhand which directs your spells. This would allow you to teleport with your wand hand, while not dumping all of your spells to the floor any time you want to teleport.
inb4 potential: “that’s a trade off for lend-a-hand” - I agree, it is! IMO it shouldn’t be.
