Goblin Raid Expansion

I know that one achievement is to get 150 Stars in the Goblin Raids, however, they become useless afterwards. My idea is to have a new random Goblin base every week.

- 1 bonus raid can be made weekly so that they are relevant after the 15o stars are collected.
- A new achievement can be added how Supercell would like to. My idea is to have one to gain 100 bonus stars, 500 bonus stars, 1,000 bonus stars.
- Allow some bases to gain Dark Elixir.
- Create holiday themed bases.

This was just an idea I had. As my first forum thread, I'll let others critique me on it.

Thanks and have a Merry Christmas,
