The casino weapons are not powerful enough to make it extreme indeed, also their power dosen't grow with grinders, only their PP pool. And if i remember correctly, they're also untradeable. So only can be used by the person whom exchanged it, and at certain point, we wouldn't use them anyways. This change g ives the new commers whom prefer to stay out of getting power leveled, could still get items that would help them early game.
I totlly endorse this one
