As a right handed person that plays mage almost exclusively left handed after the first month or so, I disagree one is more difficult than the other. Just different on occasion. I describe that 3D line as a ātennis swingā instead of a wrist movement. No issue chain casting. Iāve successfully taught first-day left handed mages to cast frost 3 in first session before, as well as other right-handed mages (varying experience levels) curious about left after seeing me do it. Gif of a perfect cast below (links to other thread where it was posted) link to YouTube video of the perfect cast.

Hopefully that will be a useful base to construct shortcuts from. The two stroke (ācandy caneā plus 3D line) also work, but including the second diagonal for the F gives a decent visual point of where the 3D line should fall. It doesnāt have to be exact and perfectly intersect, but still works well if within an inch of that intersection up/right (as in, slightly above the second diagonal, and to the right of the vertical)
Edit: since the old gif isnāt working, trying to get another once my computer cooperates and will post when done Updated link. Also willing to meet in-game for anyone that would like to learn my method for frost 3 or other spells. Also thinking on it more, ātable tennis swingā may be a more accurate description since my left elbow is close to my body, as if Iām standing at the left of the tennis table and sending the ball diagonally to the right, downward enough to bounce mid-way on my side before going over the net
