Another problem that I have with Dragon Wild Shape is that the PH 3.5 clearly says that a Druid can only assume a form she is familiar with, that said, a 12th level druid that has never seen a dragon before ever cannot take the shape. Same goes for Any wild shape. Frozen Wild Shape is awesome, but if you've never fought a Hydra before... The Fleshraker wild shape is awesome, but if you've never seen a Fleshraker before... The Dire Tortoise is awesome, you see where I'm going with this.
