I mentioned this in another thread on reclassing, and I think it's in the same neighborhood as RQ's hand-waiving; I think of features like this as in-game method to retcon the character, I'm changing their entire life and past.
I don't think that's what this is though. You are completely changing a character's abilities and stats but in terms of relationships and story progression, that still remains...you are still the same person, and you still have to live with the consequences of your past. Also the new tadpole progression mechanic...I don't think a respec will undo or allow you to change that. The exception here are origin characters other than the dark urge which if you respec them into another class that will break at least some if not all of their story as parts of their origin stories depend on their classes.
