There are some designers that follow instructions from the client and are just hands on the keyboard. That’s fine for some projects, especially if the client has a clear vision for the site, and can communicate it. Those are not the type of projects that designers enjoy, however.
We may be experts with the technical aspects of design and development, but what we really get paid for is our expertise in how websites should look and be built. We want to solve the client’s problem through user experience improvements, not be dictated to about a design.
