Have you ever wanted to upgrade a wall with the loot you got from raids but realised you have to wait 4 days for another building to finish but by that time your loot has been cut down a significant amount? Well if builders werent required we would be able to upgrade more walls at once. And its obviously no secret that walls are a very expensive part of this game so im sure the more walls you can get at one time, the better it will be for the player.
