There isn't a better system.
But the point is that you and others have openly rejected this kind of thinking in other places as utterly unacceptable.
So there isn't a better system and because I think the current system works fine for me ... anything else is completely unacceptable? I don't care what you do in your game. If there's a better system I'd interested but you just said there isn't one. So because I don't want to use some other hypothetical system which doesn't exist ... wait ... what was the issue again?
Like this is precisely why the lock picking failure resulting in an encounter with the cook was unacceptable. The abstraction didn't specify super ultra hard. It was dependent on context, on the GM making a reasonable judgment call about the extended situation aroundthe attempt, not the ultra-narrow singular act of inserting lockpicks into the tumbler of a lock.
Horrible awful affront to all that is good then.
Now it's necessary.
I hope you can see why I would find that turnaround infuriating.
The lock picking resulting in a cook appearing when they would not have otherwise appeared is a separate topic. The cook was added because just failing to open the lock was boring so the blog post suggested making it "interesting". But once again in that case I was just stating my personal preference other people have different preferences.
What's
So I still don't understand what your issue is.
