How much do walls cound toward base strength in matchmaking?
Since walls don't affect most war attacks, which use dragons or hogs, I was thinking my clan should advise members not to upgrade walls, so that our average base strength will be lower and the matchmaking software will give us weaker opponents. But first I'd like to know how much walls increase our strength score, because if it's only a little bit, it is probably better to upgrade walls to protect resources during the normal game.
Does anyone have any info about this? Thanks.
