For that first idea. Hunting will be added to the game in a future update.
Second, I completely agree. There needs to be more official maps that come with the game. It disappoints me that a game with such potential only has 5 official places to explore that actually come WITH the game itself when downloading/installing.
Aaaand for that last one... I don't think that would be a good idea. Since it's a public area, not everyone would want the same weather, and therefore if there was a way to make it rain/snow/etc. publicly, people would be fighting over which weather to choose. And I'm not sure the coding for that is even possible o_o; Lol. But thanks for the ideas, and I completely agree with the second one.
