Sam2, in his Iggeres Teiman he says that there is a Remez that Nevua will return at a date close to his time. It might be referring to the Baalei Ruach Hakodesh like the Ri Sagi Nahar.
Anyhow, Shibud Malchus is the main change. However, we know that Nevua will return and we know that the Shechina will return. Those come with many by-products. During the time of Eliyahu Hanavi and Elisha the Teva wasn’t different but there were Nisim. When someone lost a donkey he would ask a Navi, like Shaul did, where it went. Whatever I mentioned is normal and expected when the world is Kitikuno.
The rain being on time and the extra Hatzlacha are just like it was in the Midbar or under any Melech Yarei Shamayim. That is Shmuel’s Shita.
