The thing with ultralight gear is that it takes more effort sometimes to stay warm and dry. That doesn't make ultralight gear less worthy. Much ultralight gear is not made for people who don't want to think about the external issues involved.
Ultralight tents in particular depend on you adding a few crucial ingredients, including choosing a good camp site where there is limited wind, katabatic air (cold air that sinks), condensation etc, and choosing a good spot in the site where there won't be a puddle of water forming and where trees and bushes can provide some additional warmth, shelter and condensation protection. Very frequently this means that the typical backcountry campsite that most people aspire to, such as a nice lakeshore site or a spot in a meadow, are rejected because these sites will be cold, wet and uncomfortable. Much better will be a mid-slope site protected by trees. Sometimes you have to pass by the nice lake-side site or select a tent site a small walking distance away to be able to attain the kind of warmth, dryness and protection that a more robust and heavy tent will provide. Not a problem to me because the hours I spend at night are unconscious while the hours I spend hiking are enhanced by a small pack.
You can't just throw up a shelter like a Z-Packs hexamid any old place and expect it to work as well as a heavy, double-wall shelter. But with care you can choose a good site, arrange the ground sheet and other items well, and sleep warm, safe and dry. That is the trade-off. Easy warm safe and dry with a lot of weight, or warm safe and dry with a little extra thought and care. So it's only with the thought and care added that ultralight and more traditional shelters can be compared.
