Level 5 CC isn't a good thing
We've seen in the sneak peaks that we'll be getting a new troop that takes up 30 housing spaces so I've seen a few posts saying that we'll be getting a new CC that can hold 30 spaces in other words the Golem which is the new troop.
Now having 30 troops in CC will be awesome but think outside the box here. What if you're attacking a base that has 30 troops in CC. It'll be too hard to get all the loot if CC is in the centre of the base. You'll obviously need a lightning spell but farmers can't wait 1 hour to create a lightning spell and then attack.
