Hey! So I'm leveling a Frost Mage. Hit 65 and put my point into Frostfire Orb (just following a cookie cutter build). Message says I've learned the new spell. But its not in my spell book. Wtf? I see Flame Orb can't be learned until 81! Is this a bug of sorts, or did Blizz knowingly design this so I have to put points where I don't want them or waste them in Frostfire Orb to get 31 points in Frost, so I can unlock the other talent trees?
