Upgrading Walls Without Builders.

Builders have to do nothing with the walls. But walls need builder to upgrade themselves. We can't let one builder free just only because to upgrade our walls.

So I am requesting supercell to make a new upgrade for upgrading walls without builders.

Thank you.

This has already been in place before with disastrous results. So, I don't see this happening. Sorry.

very good offer.

Of course you can leave a builder free just for walls, how do you think others do it?!
