This is where PAD's format, which I'm usually relatively fond of for what it is (a parasitic, money-hungry mobile game) shoots itself in the foot a little. I like dungeons where the dungeon itself is a puzzle. That's why I think Thoth And Sopdet is the best dungeon in the game. But make the puzzle too complex and it becomes unsolvable by the non-rich, non-superlucky majority.
Requiring teams to be built a specific way to have a chance of handling a dungeon is already sketchy because of the sheer luck needed to get a great team online, but requiring someone to carefully craft a very specific key team to your puzzle dungeon is an unreasonably tall order. Not to say they won't do it anyway, but at that point it just becomes annoying when it might have been cool if the game worked a little differently.
