When you have one shot, you don't waste it on looting some regions. You go straight for your goal.
That's why I didn't understand why Asylon wandered around in Shilorak, Vorstadt and Mimiravair when they landed; they landed a spy a couple days before their main force who could have told them easily that all (not joking here) of our regions were starving (and that we had no military force to speak of whatsoever). Knowing that, why risk Morek and Astrum assembling in time? Why not go straight for Unterstrom? If Astrum had been faster to respond they might not have even gotten into the city at all.
