When's the best time to work on walls?
Ok, so I'm currently an upper-middle level TH8. Some things maxed, some things not, walls definitely not. I came into TH8 with some purple and some lighter purple/pink walls and sat that way for a while so I've been pushing to get all purple and then at least get moving on bullets.
My question is what have you found to be the best strategy for working on walls. Do them right away when you upgraded THs, wait until the end after maxing D, do it here and there and in-between?
I was talking to someone who is moving to TH7 soon after maxing TH6 about wall building and when to work on upgrading them. My strategy obviously was flawed, so I was trying to offer them some advice and I thought it would be beneficial to start work on it right away.
