The thing is, since there is almost always another kind of task available and due to the fact it's the lowest priority, you end up with a 30+ min game and no fortified walls at all. Worse, if you would like to grab a worker for a job and you don't wan to interrupt already fortifying workers, you no longer may rely on the idle workers report to not pick them up. Overall, it's my biggest gripe against the last patch, the behavior I have seen before it was waaay better than in DKII, that has exactly the same issues, and now we are back to it, what a regression. Some instances where this matters the most: Heart Attack: no fortified walls — the Garrison is fucking useless, and you just get rolled over — you lose badly. Any skirmish map — you'd like to fortify the whole perimeter don't you?
