If it didn't cost mana, Kassadin would have a free means to harass you in lane; especially if you are prone to spamming spells like Cassiopeia or Ryze, with his high mana cost on his other spells, it wou be a godsend. I also suspect it is used to keep his ganking/roaming power in check: his high mana costs prevent him from ganking too much before having to recall (in lane, you regain your mana with W).
