Why do people want Blue Mage in this game?

Depends on the player perspective. Some people feel that the current incarnation of BLM isn't true to tradition because they have no way to exploit the elemental wheel, as well as SMNS not dealing damage primarily from their egis (or having spectacular effects from the summons, or both). I feel that it captures the aesthetics of a DRK just fine through their animations, while at the same time giving them a distinct feel to their flow of combat through dorkside and mana.

BLM isn't true to tradition, but they still do what they're supposed to do and use those skills/spells. DRK doesn't, there's a *huge* difference there.
