When we started out I was also skeptical because basically so many new things come in all the time, elements change, it takes a lot of time to build a library, etc. But actually, once you have a system going, it's incredibly easy to create things in your daily work. Of course, when you first need to find a style, it's a different story. But especially when you need consistent output from multiple people, atomic design is the shit.
