yes but the fun part with more bw´s is that if you put them up correctly (takes abit of practice) you can force the enemy to fire only at your av14 wall, or if you have to give him a targetgoat (sometimes if they place their army well, its close to impossible to avoid him getting 1 side), and then you can choose to loose a boy mob, instead of him getting both your vechiles in side, and if he´s a up-to-date army, he got some anti tank, which he either can take a potshot on your av14, or more certainly take down a wagon, with a less threatening amout of orkiness (f.example: av14 on your Warboss/Nob coven tank, or av12 on your boy squad tank..)
