Talk:Future Updates/@comment-24136053-20131107002241

I think for wall upgrading, there should be an 'Upgrade Row' button that upgrades an entire row of walls for the price of the walls in the row eg. 50 level 1 walls for 50,000 gold. Not sure about the numbers, but you get it. The only downside I see is when you're a higher level when walls cost 4,000,000 gold each.
