I would think something like this, however a lot of them would be interchangeable. Like an Animist in the Morpher spot, Ranger instead of Hunter. A lot of it just depends on what naming scheme they like. Hardest one for me was the ninja path... because I get the feeling they would want to stay away from the name "Rogue" and use something more FF like.
