they are powerful, yes - but considering the availability that does not really matter. Art exhibition kits for example are so rare, I doubt I will have it at level 8 by next year. You have to be exceptionally lucky to get multiple kits in a short amount of time and loaded enough to be able to buy them.i doubt we'll be finding crow's nest kits at the dealer at any time though. that building is WAY too powerful for that
same for the abandoned asylum of last halloween
Do we get Hippodrome Selection Kits at the Antique Dealer?
