More than the storyline, it was basically because of a technical aspect. Shadow Abilities for most part have replaced Magic in SF3 and having both together can make the player quite overpowered. However, Nekki has stated they have some ideas for it. Here's what they said about Magic a while back (translated from Russian so excuse the grammar):

"Magic was originally in the plans by analogy with Shadow Fight 2. In the beta, the icon was added just like that, without thinking about this mechanics. At the moment, shadow abilities are partly replaced, but we have a couple of ideas how to bring magic back into the game. However, in this case so far there is no specifics."

The icon they are referring to is a scroll like object you could see in the inventory next to armor, weapons, helm and (at that point locked) ranged weapons. It was removed in the final release of the game.
