What do you need wishing wells so bad for? The diamonds that you gain from WW, FoY and a few other methods will soon only be available to the specific world they were won on - the diamond farms are finally being terminated. (well, maybe not terminated, but greatly reduced, since diamonds won from Recurring Quests and Quest Rewards will still be available on all worlds). As such, what real reason is there for WW? You want FoY, reorganize your cities on the other worlds so you can do GE and you will be able to have those (just not be able to use any diamonds won anywhere else)
