And what do the scrapps even do? I mean, are they are mandatory ressource for you to build new turrets? Do they generate ressources? I mean, when it comes to Spheres on Monks, on Windwalker they are essentially a bonus, giving you a beat heal after you have defeated mobs and having a chance if you killed your target with blackout kick to generate one chi, so they are more of an afterthought. Demon Hunters are a bit more exiting in this regard, with Havoc being able to spec into turning soul shards into a ressource generator, though they are the most exciting with Vengeance where they are a ressource themselves that is fully integrated into your toolkit. So what would they do? Or do they work more like dead minions on the Demonology, giving you access to a more powerful ability, in their case demon bolt, which generates ressources?
