Wishing wells apart, if gives more or less diamonds, one of the problems has created the event, is the people, that left the city "open" only to collect the well, in my hood there is a guy with the full city disconnected, except the well, which he collects religiously every day, has left 1 spearmen as defense, and occupies a place in the hood.
Luck of me, I only have one of these, I suppousse will be more "wishing well" players in other hoods,distorting the hood and the game, for the chance to get 50 diamonds every 2-3 months.The devs, must consider who is ACTIVE, not only for a person who collect daily a well, during months.
