They've certainly got the magery for it. On a different twist, I'm not sure I want the dragons being able to greater heal their owners because that seems like too much in PVP (would be cool for pvm tho, wouldn't it?). The dragon being able to ressurect the owner sounds neat as heck and it could be implemented in a way to where it wouldn't throw a monkeywrench into PVP. If they made it so that the dragon wouldn't offer a rez to the player if it was engaged in fighting, I think that would cover the PVP side of it. The low-magery dragons could perhaps fizzle it for a while, just like people at like 102 -106 magery do.
