I fully support it. And not only the jump itself must be balanced, but also the spell 'jump'. In the name of all gods, why is the first level spell is so powerful? It lasts for 10 rounds and is actually a teleport over long distances, which is just ridiculous. Higher-level spells look strange against it. Why waste a higher spell cell for 'Misty Step' or 'Dimension Door ' if you can use overpowered low-level jump.
