Sounds mostly right. The phrasing about the class/job relationship seems a bit odd, though. To clarify, a white mage is effectively still a conjurer. Being a white mage rather than just a conjurer adds benefits like job-specific actions, but you still ALSO have the conjurer class actions you've always had. The only thing it actually takes away from you is the ability to add additional actions from any other classes; jobs' additional actions are restricted to two specific associated classes rather than all of them. So you will still have conjurer abilities to use beyond 30 regardless. Groups are mostly snippy with 30+ conjurers (that do not have a white mage soul equipped) due to not having white mage job actions.
