Again, it is explicitly clear in the story. Ramiel says: "Look, in the future you're crazy powerful and can solo AVs, go find the Well. Oh, the Well has moved, guess you'll have to get there the long way." The long way is the Incarnate system we have. Now of course I agree that the actual level of power in that mission is excessively over the top, but it's an illustration.
So, you're right, it's an exaggeration, but that was definitely always the intended direction, that players can become super super powerful.
