True, but who is going to plant 3.7K 1x1 buildings? I'm not sure if all those 1x1 buildigns are motivable, there are some which aren't.
Let's put it this way. From just the Halloween Event I got 29 1x1 Gold Level'd Stormspire buildings + 26 Daily Specials + 45 Epic kits
That's a rate of 100 buildings / building levels (not including the main event building) from just 1 Event. There's 10 Events per year. 10 x 100 = 1,000
If we keep getting flooded with 1x1 standalone buildings that take Aid then you could reach 3.7k buildings within the next 4 years using only free-to-play. Some players have been here for more than 10 years. It's not as far fetched as it may sound if 1x1 buildings continue to be a trend given they're almost guaranteed to be offered as Daily Specials next time the event comes round
Even if you didn't get that many 1x1 buildings. It would only take adding
30 buildings per Event to max out on Aid
within the span of 1 year. In reality you'd have Aid issues well before then because your neighbors aren't all going to be Aiding you and your Guild probably isn't going to be a full 80 members either
