The only thing I really hated about Oracle in AA is the fact that whenever she contacted you, you noticeably slowed down. It got really aggravating when you had to be somewhere when all of a sudden, Oracle starts talking, so you have to slow down to a slow walk. On the subject of the Detective Mode, I never saw a problem with it. When I didn't need to use it, I simply turned it off. I usually just used it for puzzles, when I needed to scan an area to see where any armed thugs are, or to light an area that was otherwise too dark to navigate.
