There is no setting in Miqobot that would disable AoE rotations.
They are triggered when there are enough enemies around your current target to be affected by AoE. Depending on the job and level, you may observe it at 2+ enemies or at 3+ enemies.
Please note, however, that Miqobot does not position your character for AoE automatically. Therefore AoE abilities may not trigger properly when enemies are not packed tightly enough or if you select an enemy at the edge of the pack.
We are still improving combat algorithms, so in the future it should become better.
