Jehovah's Witnesses interpret a paradise as a CEV. For example that humans will never able to grasp the full complexity of God is a feature that will allow for infinite exploration and satisfaction of our curiosity. We'll never run out of fun and challenges. So I'm not sure what definition of paradise you had in mind. But even colloquial a paradise implies that which brings satisfaction. Even most religious people are not as naive to suggest that there won't be losers and winners. Or that a paradise would be static.
