Nexon proved something with the visitor patch.

It's physically impossible for the game to have dynamic weather and night affects without having a portal system that changes maps, like in APQ. It just isn't possible. There can be static weather affects, but not dynamic. It doesn't fit maple and it's extremely hard to do with the way maple is designed.

False. Ever used a Cash shop item that adds "weather"? Well, the effect can be kept even if you exit and enter the map. Just make a map trigger it, and VOILÁ. Maybe tweak it a bit and it'll stack with cash shop stuff.

Remember when maple didn't even have 3rd job? What about most of the stuff that came afterwards up to today?
