Mouse and Keyboard Dodge Roll Idea

I had an idea to improve mouse and keyboard dodge rolling. First it should be a toggleable option, so people can keep the current method if they want. My idea would be to have the player press and hold the space bar/dodge button, saving the current cursor position. Then the player moves the cursor in the direction they want to dodge, basically as they would anyway, only shorter. As the player releases the space bar/dodge button, their character will dodge in the direction of the line they moved the cursor, instead of toward the cursor. Altogether, it should still be basically as fast as just hitting the button, with a quick little mouse movement while you release it.

I've had a few issues where I wouldn't move my cursor far enough past my character and still dodge toward a group of enemies, putting myself in a pretty bad spot. I think this could give a fairly quick alternative that keeps ranged attack users focused on the enemy, while still having the flexibility to move in any direction with the mouse.
