I thought of this earlier, but to show the passage of time besides day and night, would it be possible (or if it is planned) to have zones go through the seasons? Spring, summer, autumn, and winter? The Black Shroud would be a good place for it. It already seems like a deciduous (a forest that has the seasons, like the forests here in NA). I know that the passage of time is quite fast right now in the current game (day and night cycles), but if the seasons were added for realism, there could be different monsters and drop items that show up at different times.
It's a thought, and I'm sure it could be implimented later on in the game's cycle.
