Behaviour dedicated map balance person
Here's an idea:
In addition to that dedicated map design person man, you should also hire someone dedicated to the map balance.
He would mark loops as safe/unsafe/very safe/ultra-long-near-infinite-loops and add additional option for the idea if survivor can see the killer while looping. It would take a while to check all of the maps but after that process is done, map generation algorythm can be altered to for example: Only add 3-4 safe loops, only add 3 unsafe loops and so on.
That guy would probably instantly remove all of the insane loops from the game like ironworks of misery window that simply takes too much time without any counterplay other then bringing bamboozle which still doesn't stop a survivor for running to the nearby loop for that 20s.
You can either do that or straight up gather feedback from experienced players in the game that know what they are doing like streamers and such.
Also... totem spawns can also be fixed by that person because as of right now NOTHING IS BEING DONE about them. Only time totem can really stay hidden for longer is the maps with confusing design like the Lab or very rarely school map.
