It does appear that the base classes and races have received some very exiting options to bring them on par with non-standard races.
My concern is that it raises the power level of a game that would normally only use the core rulebooks.
There are a number of options that could downbalance every character evenly across the board so that a party of level one adventurers created with this system have the same difficulty versus a CR1 encounter as a party of level one adventurers created using the SRD would.
I know that I am not alone with this concern, but I am very likely not with the majority.
I think that its very important to keep this balance facet in mind when working on the Pathfinder RPG product. Perhaps it could be included as an optional feature.
Please, everyone, if you have ideas to help downbalance the system fairly and across the board I'm all ears.
