Well... that depends entirely on whether the exchange rate for Talents with the respec guy has changed.
In vanilla, it used to be that you could trade in one Talent point and get ten ability points and five ability points gets you one attribute points... in other words, you could take a point you'd otherwise spend on Know-It-All for +1 INT with a penalty and instead end up getting +2 INT with no penalty.
EDIT: Update, the Talent exchange rate has been drastically reduced (from 10 to 1). So go ahead and take this one.
