I have quite a few builds that are playtested like these ones:

Gameplay and building is my stronger suit so I tend to like to play my builds. I work full time too so don't always have the time to playtest all my builds and I mod and I playtest, so time can be limited at times. But I try to playtest my builds when I can. Shell challenges are a bit harder to playtest for, but tried sharing the ones I know I've playtested with and if there are any routing issues I don't know about, sorry in advanced, I'll try to fix them. I admit it was easier to playtest when I had freetime, but I find myself busier during than pandemic than before it.
