Neighbors should not be allowed to wreck the wheel while someone else is trying to get a prize – especially because people spend diamonds on the wheel. The "refresh wheel" should be locked for 30 seconds after each spin. This is very similar to the programming in the Antiques Dealer.
But to have something like that, we would need the game to not be managed by corporate as*****s. So of course, it will never happen.
If that were to be the case you might wait nearly 15 minutes to refresh a wheel while watching someone else spin out for a prize you dont want. If they beat you to the spin they could keep it locked until the wheel ran out.
So not only would you be less likely to come upon a prize you want. Your available time to spin in game might be hijacked by someone else.
The 30 seconds on the AD is to allow a new bid to come in and stop last second snipers from simply dominating by adding 1 point to the bid every time.
By delaying a refresh you're not accomplishing anything but adding lag to the other 70-ish players in your hood because you feel like you deserve the prize.
I spent a lot of diamonds on this event. Made out like a bandit. And spun out several wheels; also refreshed nearly 400 in my farms just for funsies. Which would have taken me over 3 hours if that delay was in place.
