Well in general I agree. Compare: Standard Shaman --> Kardush the Firecaller --> Druzhag All at 100 points. Would anyone take a shaman really with an army of less than 2000 points?
Any spellcaster is squishy if singled out by a hero. It's part of the tactics to keep em safe and part of the enemy's need to hunt em down if possible.
I have taken Druzhag and kardush as an Isengard player - Though Isengard is by the Misty mountains and who knows where Kardush hangs out....
, but I haven't *quite* rationalised taking a Nazgul just yet even though it is suggested nazgul might go and visit Orthanc if needed...
While good players may bemoan all the cheap casters (and I agree something is up with the Nazgul as written... Mastery 3 jeesh) Evil factions get fewer real meaty epic heroes than Good factions - basically less choice. Isengard and Misty especially. Instead we get the spell casters, and not that many of them (excluding the Nine) and of course more Monsters and some Monster heroes, though again a lot of these aren't that hard to kill. The mix is different for the two sides.
