While I, too, like the idea of multi-role classes/jobs, I can't quite see your vision for it here beyond the system itself. What makes it fun to you? Even if just a glimpse, could you tell us what would be so neat about these different role-twists and why multiple-roles-per-job would be better in your opinion than the current DD/Tank/Healer mostly homogenized niches (+/- indirect contribution methods via still relatively minor survival or external throughput utility)?
