I think there should definitely be some end game content. I appreciate that the core style of the game is an RPG with a defined story, but that doesn't mean there can't be anything to do after you complete the story. The combat in this game is great, it's a shame that there's a finite amount of enemies in the game.
Hopefully mods will fix this, though right now it's slow going while people figuring everything out, it may be a while.
