I have been playing around with the map editor, and I have a really good idea of what I want to create. But it's extremely time-consuming; it took me nearly two hours just to place a small cluster of buildings.
As you get further into the game, enemy encounters on the road occur more frequently, and they are usually better-armed and/or in greater numbers. And there is always a chance that a nearby patrol will join in on the firefight. But you won't face constant waves.
Oh yeah, the editor is very time consuming..at first but as you get familiar with tools and objects, things will easier and less time consuming. You will still invest a few hours on a map but at least it won't be 12 hours

, depending on your size and attention to detail of course.
A few tips that may help- some you may already know.
1. Use the different camera speed 1x, 2x, 4x, 8x.
2. Test/Explore A LOT. This will save time in the long run.
3. Multi grab tool is a life saver especially when it comes to fences.
4. Time of day and weather settings can drastically make a map better.
5. If you have OCD, this is one time when it works in your favor as every rock, structure and object will be perfect!
6. If you care about getting higher rated maps, keep them small to medium. No one likes playing huge maps.....except me 👍.
What system are you on BTW, I'd love to play some of your or anyone else here's maps, I'm on PS4.
