Instead of proposing drone runs in Overworld, why not just to show illuvials stats when scanning them? The idea in OW is to find good Illuvials for using them in Arena, but is very wasteful to have to enter each time to battle, realize that there is not any worth illuvial, and respawn in the Obelisk for continuing with the next illuvial. We lost so much time.
Please. Make things easier.
