gunners already ran thru and shredded this area and this juggy decided he was going to break thru the wall at all costs. Took forever and when he was done, MEH - not interested... Walked away. Faulty AI? Pics below http://imgur.com/67UHlUq Gonna tear down this wall just because... http://imgur.com/3jovKEy Nah... No need to go in there...
What likely happened was: The juggernaut decided to attack the closest target the juggernaut started destroying a wall to get to that target (once they start attacking a wall they don't re-evaluate their target until the wall is destroyed or they are knocked back or stunned) the gunners killed the target before the wall was destroyed, and moved on the juggernaut didn't re-evaluate the target until the wall was destroyed the closest target was no longer inside the wall, and the juggernaut went for that instead this is how almost every troop currently operates and always has. The optimal behavior would be that when the juggernauts current target is destroyed, even if he's currently attacking a wall, he re-evaluates targets. He could do this before or after every swing, possibly. The one issue that can occur is that if buildings keep getting destroyed, he could keep hitting a wall one time, realizing his target is dead, and switching to a different wall, never destroying one or making progress. +1 if they decide to re-evaluate this behavior, but only if they promise to properly test it this time
