After a few sessions with the new rework, I believe the original method of pressing the second button while charging is more intuitive, as using a wisp to create a wisp arrow in the air by hitting the opposite direction feels awkward in practice. I believe reverting the nspecial triggering would be best, and possibly the strong attack empowering as well, however the current method is far less awkward with strongs as you are not moving while charging. I additionally would not argue against requiring a wisp arrow charge to be stored for empowering smash attacks, as that seems like just a bit too much, at least as long as the opponent can hit her to remove her charge as they can currently. If you are to implement that arrow charge requirement, remove the opponent's ability to take your charge.

My main problem with the opposite direction method for neutral b is that it makes it really hard to do an uncharged b-reverse arrow
