That's only as much of a problem as you make it. The system being made to be simple as it is, size doesn't require a mechanical impact. Until things leave the 'possible PC' range at least.<br/><br/>Looking at the present races this 10-foot anthro dragon is merely Dragon Beastman. The extreme size giving physical advantages is just putting the free points into PHY. Add in a racial talents to gain access to things like a breath weapon and presto, the problem you see is proven to have never existed.<br/><br/>I will also direct you to the Dragonborn of D&D 4/5e fame for a precedent of anthro dragons being a standard power race. It happens to be my favorite option in those editions.
