Basically, this job would use an Axe and Pistol (which will be counted as a single weapon like the Red Mage's Sword and Focus are) and would be a "minimal magic" job like Machinist (Ranged DPS) and Gunbreaker (Tank). You would learn the job at Limsa Lominsa.

The gameplay would be based on damage over time and keeping those DoTs up, using Axe swings and Pistol shots to keep the damage going. I hope I am making sense. Posted a similar idea via another thread, but don't think I got my idea across right.
