Facebook connect

The game is great except that when I created a Facebook to get gems for the game then later it said I needed 15 friends to expand my land and having to do with friends and I dont want to add friends to expand my land I want to spend my gold. I mean whats the purpose of the gold if it is going to stockpile and there is nothing to use it for. The issue with adding friends to expand land is the worse thing I mean what if I dont want friends to expand my land can you change that especially if someone who doesnt have Facebook how will they expand their land Im on level 36 and there is already a problem with expanding please resolve issue soon.

Hate this stupid app about Dragon City - Breed & Battle!, v4.7.2
