Part of it is that the monster generation has been toned down sometimes around.... 2011? There were a lot more beforehand. However, the big change came with the new estate system that allowed the realm to colonize the whole space of Dwilight. Before that the rogues could increase in size and merge while in rogue region, and when you saw them arrive at your borders they were sometimes huge. Most hordes were in the 3-6k range, but roughly once every two months you could expect a 20k horde to appear south of Morek.
Those were the good ol' days.
Fighting 10-15K CS undead and monster hordes coming out of where Aurvandil was when they came through the Tower. . . every week -.- Fight a horde, refit, fight a horde, refit.
Actually was the most fun I've had in a while.
