Could you elaborate on what you mean by "hard to control"? You have complete control over how fast you move (from completely stopped to 3x base speed), and it's basic WASD movement with very little floatiness, so I'm surprised to hear that it's difficult to control.
If you push the blue bar to the right, you'll move faster. You can counter this by shooting more often. Try to balance movespeed and attack rate to not push your blue bar too far thus making things difficult to control (and nerfing your damage)
