Age of Wushu kindly disagrees. The title is preparing to roll out dynamic weather in a forthcoming update, and a new teaser trailer hints at the possibilities that it could present.
The trailer shows a character running through a storm at night. Sheets of rain come down as the occasional bolt of lightning illuminates the surroundings for a few seconds. Check out the video after the break, and don't forget your poncho if you're heading into this title!
