hi supercell...just my opinian...if you feel this ideal opinian...you can think it...my opinian is...if you can make button to upgred wall many at once...then click one by one but price still same each one wall.....still same when edit base and make layer wall....if this opinian is bad...just ignore it ..ty supercell for good game

When you select a piece of wall there is an option to "Select row" so you select it and you can then proceed to upgrade the row you have highlighted
