DMX can be boring if all the Lighting Director(LD) does is sync the lights to each other. Just like your music sets, the lighting needs variety as well as matching the emotion of the music.
I feel the lighting can enhance the music and emotion of the floor or be repetively boring. As a mobile, I travel with another dj. My role is DJ/MC and his or her role is DJ/LD. I guide the LD such as slow song next or blackout for a pause in the song, but they know that are responsible for mirroring the song being played however they see fit.
So far, I have been happy with the results. Sometimes we trade off because I need a break from the song selection and I want to operate the lights for a change of pace. It works good, but I pay my DJ/LD fairly well. Typically 10-15% of the gross of that show for someone who is experienced. Which usually ends up being similar pay as if they worked for a multi-op as a DJ.
DMX can be boring if the palette of light options are limited, but in my opinion not as boring or visually confusing as letting the lights go on “sound active” all night. For me color selection is the most important part of dmx whether it is complimentary colors or similar colors.
