Level 7 walls (purple): are they really necessary for a late TH Level 8 base?
I am very close to maxing out my defense in my TH 8 base. Now I am wondering whether I should upgrade my walls before I upgrade my town hall. Because both pink walls and purple walls take 2 wallbreakers to break through, so they are pretty much the same. But purple walls are expensive - they're 200,000 a piece. However, some say that I should upgrade my walls to all purple when my town hall is at level 8. I am confused. What are your opinions?
