First of all I have to say sorry for my english because I'm spanish.
Yes, this base is for only 2 storages of each type. Why?, because there are only an update that needs the third storage and it is for Pekka 3, and most players I know come to TH9 before get Pekka 3; and two storages are better to protect than three. Maybe you think that three storages are better than two but this thread is not for discuss that, this thread was made because there aren't any good base for Farming in TH8 with only two storages and I wanted to make my own. 
- Good design and symmetry
- Good air cover
- Good mortar cover
- Centered dark elixir
- Storages very good protected and not in the same cell
- Castle range into the walls
- Dark elixir extractor into the wall
- Centered castle
The only con that is can see is that the mage towers are not very centred.
Hope you like this base! Please comment! Bye.
