It will be like adding a new job. Right know we have jobs with no a base class. So example I have a bow equipped am a BRD with skills and as soon as I equip a staff and a WHM with all new skills an traits .So it would be basically the same thing. U equip a flute u still a BRD but u have all new skills and traits like(like switching a new job) u will really just be bard by name Lol there are more than enough weapons to have new jobs. But I would like a healer with a flute lol
