Correct me if I'm wrong though, because I haven't made it that far in D:OS yet, but according to the Wikia, once you get the Hall of Darkness in the Homestead, you can exchange a Talent point for 10 Ability Point, and then 5 Ability Points for 1 Attribute point, resulting in 2 Attribute Points for each Talent Point.
Doesn't this pretty much mean that virtually all +Attribute Talents are a bust? Why take Know-It-All for +1 Intelligence at a penalty, when you can exchange the Talent Point for +2 Attributes (which you'll spend on Intelligence) instead?
Or am I missing something really obvious?
