There's a lot of these, I agree with. However, one thing that has not been mentioned that sprung to mind was...spontaneity.
I enjoyed when mistakes were made or things went against the standard plan of the show (i.e. hosts flubbing lines and laughing it off, or Pat/Chuck landing on Bankrupt/Lose A Turn) and, unless it was severe enough to stop production, the editors kept it in. It made the show feel more natural and enjoyable.
Now, even the slightest flub gets edited out, and it just feels sterile to me. I hope I'm not the only one who thinks it, but I enjoyed the "just go with it" attitude.
