That's because fire drakes cost a lot of gems, and losing that many gems isn't fun. But I think they're underrated, personally. Look at it this way, what if all Aka-oni could cast the fireball spell, for no fatigue, 3 times in every battle. Would that be fair?

Personally I would favor the precision boost. They would be pretty worthwhile with a bit better precision without being 25 gold mini-mages with limited immortality.
