There are some valid usecases to use rolling or some bleeding edge distro, like if you want to contribute to KDE or similar project you would want to track latests library versions, but for doing say a web dev job and soem enterteminent an LTS distro works better, you do not upgrade and you have the surprise that GNOME removed yet some new feature you were using, or soem stuff in Plasma broke and now you get a ton of notifications about something not working, or maybe you did not read the Arch forums before upgrading and you had cool package Y that conflicts with cool package Z and now your system is unbootable and you need to fix it instead of doing your actual work. (Arch fans should first Google Arch upgrade briked my system before commenting that this never happened to them).
Btw I used Arch in the past too when I had more free time and loved thinkering with my system.
