EDIT (1/29/15): Wow! 2k views! :D Anyway, I'm at 52 walls to go till all Level 6. Thanks for everyone's help!
Hey everyone,
Currently I'm a TH7 with maxed defense. Collectors, barracks and troops are another story.
However, at this point I think I'm ready for an all-wall spree. My walls are in really bad shape, with mostly Level 5, 20% Level 4 (:eek::eek:) and a couple Level 6. Any tips on how to farm for walls? Troop composition? etc.
As the max wall is purple (Level 7), I'd like to at least get to 50% pink, 50% purple.
Thanks for any input.
