No one remembers Flintlock from Final fantasy Tactics A2? It was bad because he had to charge every time he wanted to use a spell. But I think it would be a cool addition for the game as a DPS. Elemental shots, some MP/TP regen shot that regens in an area or Shield shot that buff resistances too. Some CC like a blind shot or something to push the enemies. He would have the longest range of the game and he would deal a lot of damage, but he would need to charge everytime he uses an ability.
