Don't start yelling at me and telling me that I'm blind before you've checked if I'm right. If it turns out that I'm wrong, I apologize for wasting your time.
I'm able to find the specialization for all other classes in the game in their spellbook, but it's missing from my paladin's spellbook and that of all the paladins I have asked. I've even read through every single ability available to my paladin including the ones in the general tab, and I still couldn't find it. I haven't checked if the passive spell is simply invisible, or if it's completely gone, but it could explain why people are whining so much about paladin lately.
