Eberron tends to have lower level good guys with liberal NPC class levels to pump up the skill levels but keep the subpar to PCs. Evil NPC are a whole different matter, besides high level guys who tend to do conspiracies they also suggest that some more active villans be scaled
to the party. In essence, these villians are coming into their own just as PC are able to deal with them.
Judging from the reoccuring "NPCs have too low levels" thread on the WotC boards, it seems that there is vocal contingent of GM's who think the greatest threat to a good guy NPC isn't high level evil doers but his own players who will turn his world into "their own personal sandbox" if doesn't have epic-level kings to keep them in place.
I've had to run herd over such players before, they have my sympathy.
