I've played in Cyrene for most of my Achaea career, and if there's one thing I always really liked, it was the weather. Cyrene would have rain in the summers (enough to make jokes of) and blizzards in the winter, and it captured both the changing seasons, and the feel of living in this cold mountain valley.
A while back now, though, we got the changes to the weather code, and while some of the changes were nice (temperatures that made sense! Ambient messages!) the end result feels, at least to me, like a step down from the old code. Instead of precipitation, we got more places where the wind will block your attempts to speak (which is more annoying then immersive, I find), and places where there are perpetually gale-force winds that will knock you out of the sky.
Even worse, seasons seem to have been lost entirely. Cyrene now sits at a comfortable temperature year-round, with no rain or snow or anything. We have a set temperature in a realistic range, instead of the completely dysfunctional ones in the old system, but it still ends up as far less immersive, I feel, because that temperature still doesn't make sense. And there's no rain, or snow, or any precipitation at all, it seems. What was once an interesting feature of the city is now just gone.
Between what we have now and what we had before, I honestly think the old setup worked better, and so, if it's not likely that we'll see weather and variable temperatures added under the new system, I'd like to seriously suggest that we just use the old weather system again. Given all the weariness of how clothing level is calculated, and how the ambient messages work, I think that little immersion would be lost, while a whole lot more could be regained.
