I would love that. Imagine rain so intense that the terrain turns into mud so thick that you barely can walk in it and have to use a sparrow to get anywhere. Or the other way around winds so strong that using a sparrow would just be insanely difficult because you would be like a leaf in the wind... literally. Dynamic weather would be great but I really would love them to take it one step further than any other game has done before and make the weather acutally influencing the environment. Even enemies could retreat from their usual locations to than safer environments so that farming buildings for example would be more dangerous under certain weather conditions because all the caves and buildings would be full of enemies while outside there would be less enemy fire but the elements themselves that would make it hard to farm. That would really be immersive and that would really be the next gen gaming experience that at least I was hoping for on the next gen consoles. This generation in general is a massive disappointment in my opinion. Even one year after release there is only a handful of aaa-tiltles and way too many indi-titles would look like I'm still playing my old SNES at best. And those aaa-titles are about 90% remakes from last gen games or cross-gen titles that give you slightly better graphics than on your older system. I think implementing something like the OPs idea would give us a little more next-gen feeling and could make this game shine.
