What do you consider 'gameplay breaking' type powers that need to be capped/taken out? In essence, Wrathion has a bunch of showy magic but his biggest trick is that he's an actual dragon, and can shapeshift back and forth from that shape. He's not big enough to sit on a house and smash it, but he's big enough to carry people. 75% of the time that isn't Constructively Useful because dragons cannot sit inside small human houses and talk to people, but I know being able to straight up fly away from trouble is sometimes bordering the gamebreaking land for people.
