The system had options last time. If you wanted a new spot(too hard/couldnt find) you took the edges. Options. D-art was also implemented to help a lot.

This system needs the option by raising the duration to ask questions(sucks but opens opportunity - you can always just go searching anyhow with the d-art).

while it may take 30 minute to get a hint(1/3 chance for the wand you want) it should also reset the spot each time asked. Giving you an opportunity get a wand that you can actually get. Even if it takes you 3 hours to get the hint for the wand you want reset in a place you can get it. Obviously, its always in your best interest to get the wand as soon as you can. So the incentive to collect is there always.

Simply because if it might take you 30 minutes to get the one hinted at now.. who knows how long it'll take to get the reset from the proper want hint reset - and in a place you can collect.
