Having played bass and ran the desk at a few different churches down the years, I would agree. You can set it all up in a school hall the hour before, or you can have an install using much higher range stuff than the gear we’re talking about in this thread ... and it makes no difference at all if the person behind the desk doesn’t know what they are doing.
The main problem I see is that people (esp guys IME) approach it as a gear thing, spend hours and hours working out the gear, moan cos they could only afford desk X rather than desk Y, know all the ins and outs of if the K12 would be better than the RCF equivalent.... but have utterly no expectations that mixing is a skill like playing an instrument that takes skill, attention, some discipline and most of all ears to learn...
anyway rant over
