Dragon hunting is actually very character exp inneficient since you can get one unit less total from the map. I'd recommend Flame Dragon once you're able to take it, or Remnant Vanquish 3. Those will give you the most units while still not taking the biggest toll on your gold (Return to Ruins is actually the most efficient, but it will drain your gold like a company going bankrupt).
