... It's not that great, really. You're restricted to Small and Medium dragons, even at 20th level.
Even with the size restriction the feat is awesome.....the versatility is amazing. Just look at a young adult shadow dragon. 80 ft movement, 120 ft fly speed, +19 natural armor, full concealment in all but full daylight (or a
daylight spell), immunity to energy drain, a breath weapon that deals two negative levels, frightful presence, DR 5/magic, and SR 20 (not great, but it's there).
Versatility is the key, Amethyst dragons grant a Force breath weapon, and all gem dragons allow you to plane shift through the material and inner planes.
Silver dragons give you immunity to two elements, and with the Druid spell
Energy Immunity (also in the Draconomicon) you can eliminate your energy vulnerability, making you immune to 3 elements. They also effectively grant you 3 extra wildshape uses per day via its
alternate form ability.
Pyroclastic dragons grant you a
disintegration breath weapon (low DC, but useful against walls of force, and the like).
Faerie dragons grant a 100 ft fly speed with perfect manuverability and SR 18.
Oceanus dragons gain smite evil and water breathing, in addition to DR and a decen natural armor (+13).
Rust dragons gain a rusting bite attack, DR 10/magic vs. metal weapons, and SR 16.
Tarterian dragons gain Freedom of Movement.
Several dragons offer fairly high-damaging breath weapons, such as the Battle Dragon (8d6 sonic), Silver (6d8 cold, IIRC), and IIRC, both the Deep Dragon and Song dragon from MoF have 8d8 breath weapons.
Not to mention nearly all grant Blindsense, Keen vision/Low-light vision, Darkvision, immunity to magic sleep effects and paralysis, and scent.
Recently on the Character Optimization boards on the WotC site someone compiled all the available dragon forms, and their abilities. The feat is really quite versatil.
