It's not completely useless, but Catalyst --> RoA does more to relieve your mana problems than Nashor's, and has the very big bonuses of survivability and sustain in lane. The fact that Nashor's allocates such a large portion of its cost to a worthless stat (for Kassadin) like attack speed makes it grossly cost inefficient.

If you're really hung up on CDR for some reason, there's absolutely no reason to take this over Morello's Evil Tome. It offers more AP, more mana regen, slightly less CDR (only when you don't have blue, which should be a minority of the time - with blue, they both give 15% CDR for all practical purposes), and none of the worthless AS, all for 385g cheaper. Not that I would ever build Morello's on Kassadin either, but it makes far more sense than Nashor's.
