Well, it's only in the planning stages currently so my details are very limited. I can tell you that it will definitely be a lower mid-rate, between 30 - 50 exp rates.
I also warn that I'm not a huge fan of "spoiling" players like most high rates do. (Obviously if a suggestion is made to change something and that suggestion has a lot of support I'll consider it.) For example, I'm all for Warpers but I feel that the dungeons requiring quests in order to access them should be quested. (Though I will likely have the Rachel Sanctuary donations all paid off, that's a bit too extreme for a new server.)
I would also like it to be Renewal (I'm well aware that Renewal is far from complete currently) and feature the 3rd Jobs.
Note: Nothing is set in stone, however.
