For the time being I'm holding off on buying it to see if I can do without. 400gems is quite alot for any character or building, specially when after event is useless.
We already have to store walkers and floaters if we have them all.
I'm sure many will fall into the trap of tapping thinking they are spending Crowns as it's placed in the Town House where we have always used Crowns.. before realizing it's Gems!
