I think this is a really valid point. Before you can even think about touching a lighting console, the rig needs to be working. Powered, data cabled, and addressed. If the rig isn't working, this is a huge learning curve for those that are not in the industry. "DMX", "Personalities", "Start Address", "DMX Splitter", "Universe" are all just jargon. This is the exact problem we try to solve with RigSync. However, in most cases, the fixtures are sadly not RDM, and so this all falls down...

The aim of FLX series consoles is that they are as intuitive as possible, without limiting advanced "industry" users. There are some consoles solely aimed at non-industry operators, some aimed at industry professionals, and then FLX which is definitely designed as a "hybrid". If there were particular workflows you found hard to get your head around, I'd love to know - perhaps we can make some changes.
However, what never ceases to amaze me, is the speed at which students pick up and learn FLX. I was running console training only the other week at a school, and before I had finished explaining what the different faders and buttons are for, a couple of students that had never touched the console were controlling lights, and recording them onto playback faders. Anyone under 20 - 25 seems to just "get" FLX. Why? Good question. Growing up with an operating system in your hand (smartphone/tablet) is definitely going to help, but I also wonder whether an element is that they have never heard the term "fader per channel". If you don't know this philosophy, why would you expect a single light to have several faders to control it? Working left to right, they see the fourth light, raise the fourth fader on FLX, it comes on, tap blue on the touchscreen, and that light is now blue. Happy days.
This is a real issue, and something we see regularly from a support point of view. There never seems to be any handover when the designated school technician leaves. This is where from our point of view online training works well. The teacher who wishes (or has to!) pick up the reins can join an online session on their tablet, sit in front of the console, and work through some examples with their lighting rig.
I hope this hasn't come across as me ramming FLX down your throats. I'm not a sales guy so had no intention to! Just my personal outlook on the topic.
