Best option to keep battles from getting wonky looking would be to increase movement speed only when neither you or anyone in your group has any enmity generated on anything. A 25% boost would be as far as I would go and don't let it stack with any movement gear. Movement gear would be used for kiting only. Honestly though a speed boost is not REALLY needed. It's quite easy to get movement gear for almost any job if you care enough to put the minimal effort in.
