Honestly, I like the shorter CD on manafication. If your goal is to get an extra use, keeping it on cooldown is the way to go. Even if you decide not to go that route, it makes the job able to adjust on the fly if you need additional movement. That can be avoided with better planning. It at least gives you an additional option in the red mage game play.

Also, not sure if anyone has thought about this, would you like to extend the timer on the acceleration buff to 30 seconds so it matches grand impact? With the ability to do multiple melee combos and keeping acceleration from capping, sometimes I find myself dropping the acceleration buff. I could start a new thread for this.
