Pumpkin exchange rate
Halloween is one of my favourite times of year so I'd quite like to collect the buildings this season, but surely someone at EA has made the exchange rate between pumpkins, creep tokens and ghost essence so poor that I cannot see how it's achievable!
The exchange rate for pumpkins to creep tokens is around 0.23, so you'd need to collect around 7000 pumpkins to purchase the Warewolf Lair. You'd need to collect around 6000 to afford the Ghost Mansion. I don't see how achieving that is remotely possible withing the 28 day duration of the season.
Of course having to exchange pumpkins for other tokens is over complicating the process in the first place. Why not just collect pumpkins and spend them?
Obviously it's a money grabbing exercise with 'features' like the seasonal currency boost...
