As promised, here is my UI using the Naga Razer Epic.

The idea I had incorporating the Naga is pretty simple. Since I’m new with the mouse, I felt like I needed a guide to what buttons are available to me. Those are the “N” buttons on the right side of my action bars. I configured the keybinds using Bartender4 and the main framing is ElvUI. Those are the main ones. I’m using mouseover macros with the Naga buttons so I find it pretty convenient in both arenas and battlegrounds. Here’s an example of a macro I use:

/cast [@mouseover,exists] Shadowstep
/cast Shadowstep

In English, you shadowstep the mouseover if it exists, otherwise just shadowstep your current target.

As far as reviewing the Naga is concerned, I’d say it’s an excellent mouse for MMOs. My reaction times are improved significantly after the expected learning curve period. I’m still getting faster with it, though I do have trouble using the bottom 6 buttons (7-12) effectively.
