So, here are my thoughts on it...
I agree that it can be intimidating, it was for me. I think LEM customers do need to know about it; when I was using LEM before knowing about it I felt like I was being pushed around by this invisible force and it was incredibly frustrating. Understanding how a product works is always key to being effective at using it.
My recommendation would be to try and come up with a creative way to explain it or even show the concept in a picture to simplify it; take the intimidation out of it. SolarWinds has some great folks in the UX team, I am sure they could help with this; in my experience technical folks like myself are not good at making things simple.
