I'm fine with 3rd party utilities giving me the information I need instead of Toady, although I do think it would be nice if he backed down on his position regarding making some effort to support 3rd-party UIs.
Still, it's not a matter of making "perfect decisions", it's a matter of knowing fact from fiction. Without having hard numbers, it would have been impossible to know that attributes were rusting. If you are going to see whether one thing has an effect or not, you need to be able to measure that effect.
I don't see what the point in playing the game is when you have no control over the outcomes, and to have control over the outcomes, you need to have at least some idea as to what the consequences of your actions are, or you might as well decide by cointoss.
Superstitions like the idea that personality (such as creativity) affects what will be engraved are the result of simply taking wild guesses at the consequences of your decisions, and detract from the experience of the game.
Besides which, what is the point in playing a game that goes so far out of its way to provide so much detail if you simply can't see the detail, or understand what is going on? You might as well play a simpler game that you can at least understand if that was the case.
