And when Karibash said send forces to scouted regions to burn down their RCs, people rolled their eyes... oh well.
Not really. We tried to do exactly this when we marched down the Penninsula. Problem was we have a huge Aurvandil army on our tail, so we couldn't spend more than a turn or two in a region, and we didn't have the Noble mass to knock out the RC's in that amount of time AND preserve hours to move on to the next region to stay out of striking range of the Aurvandil army.
Ultimately, we got bottle necked in, tried to shoot a gap to get out, and then got crushed (thought we expected that would happen when we went down there).
