It was one of my favorite things in the game in my early days of playing and I wondered why the devs stop implementing them to other elements after giving each to Mona and Ayaka.

But then again, the original purpose probably is to have a character be able to traverse bodies of waters easily so Hydro and Cryo are the best candidates for this ability. Still, I wish we have a representative from each elements who has the ability to alternate sprint. Would be cool to have them even if just for aesthetics.
