Yes, please separate CTF from “Real word” boxes. That would be awesome as I “hate” spending time on a box just to realize it’s initial foothold is via credentials stored in image by using stegenography etc. I’m sure there are people who enjoy solving puzzles and they would probably think the same for “real world” boxes.
That being said, I really enjoyed and learn a lot from Vault, Dub, Active, Reel, RedCross and few other currently active or recently retired boxes. These boxes were great for me as I’m probably not that experienced as author of this thread.
