I agree a bit with dragon transfomartion. FoV is awesome, and playing as Dragon isn't very fun, because it usually brings nothing to story, no quests - escort mission was good, however.

Extended dragon skills?

Warrior Dragon - you can do this, rightclick on the mouse while being a dragon (doesn't work in Talana's vision)
Ranger Dragon - There's no Evade skill against ranged attacks, but with some skill you can usually evade them anyway (exception - Zagan's Cave)
Priest Dragon - You can Summon Wivern.
Mage Dragon - you have that explosion skill, fireball, just like the mage.

But I agree, if dragon wasn't so dull even in the area of skills (and making quests! There should be flying NPC and their quests, main or not), well, maybe then we'd like playing as him more!
