An awesome update would be the goblin king for any townhall level! Because there is the campaign levels and there already is a goblin king once you get 150 stars on the campaign you capture the goblin king and he becomes yours! His special ability is either jumping over the walls or sending lightning strikes on gold, elixir or dark elixir. This should come in the next update.
The goblin king will be on the store but locked. It will say 150 stars needed
If you already have 150 stars then you go onto the store (buildings) then click on the Goblin King and you will receive him for free.

I think this should really go into consideration as many people want the Goblin King as well as a well-known Clash of Clans youtuber
