It sounds like people believe that 7.0 is going to be a PSO New Genesis situation where they are going to retain job names and skill names but drop us in a completely new area with no affiliations to previous content and I don't think that is the case. We will most likely start 7.0 interacting with people we know and have a history with, and they will speak with us as though we have already done all the things in the previous arc. I can't imagine any beginning of 7.0 where we will be in a position where we know no one and nothing about the world around us when we spent the last story arc on nearly every continent playing a major role in historic events. Even if we start 7.0 on a different shard they would have to explain how that happened.
