To build walls or not to build walls

get all the walls, but keep them at low level.

Build the walls, push it to purple/lv7. sooner or later you'll need stronger troops to feed to your clan. I also have a 2nd account. currently at TH8. it's not maxed but it has lvl7 walls and it's paying off when I have to save up for something to upgrade. It now I'm planning to make it to TH9 so I can donate lv2 witches.

Just don't do them because that's how you roll, and tell your attackers "Suck it up!".

Do them, but keep them all at level 2, because level 2 walls look cool.
