I'll have to disagree with some people here about the most mobile magic DPS. It should be Summoner, not Red Mage. Summoner can move around with minimal loss due to Ruin II being only 20 potency short from Ruin III and Ruin II can potentially become Ruin IV which is also instant and obviously more powerful. A lot of its abilities are ogcds as well. With the Dreadwyrm Trance change (Ruin III becoming instant) it's even more mobile than ever before. Meanwhile Red Mage needs to successfully cast a spell first before getting the instant cast buff. Still very mobile however.

Other than that, they are right with the other roles.
