I think we're going to see a chapter to this story where the dragon slayers are going to have to figure out why they arent strong enough to kill dragons, if dragon slayers actually killed dragons in the past. and how they can get that power. I'm getting the feeling that the dragon slayers are more connected to zeref than we know and unlocking there power might depend on him. I also think Mavis knows whats going on and has some information on why the dragon slayers are so weak.
