While i was reading through the Advanced Class Guide I was wondering: what about the favored class option? will the favored class of both "parent" class be acessible? will there be new one for the new classes? Will you have to chose one of the "parent" class, and only have access to it's options?
Some things you might have to wait until a bit closer to its release to find out. I don't remember any definitive talk about favored class options myself.
This is why I'm not playing any of the ACG classes past level 1 in PFS until the guide is published. I want to know all the changes and additions before my character is "set"
