A rather observant player on Chaos (can't recall his name at the moment to apply credit where it's due) noticed that Armor has been added to the training point list.
Is this change intentional...well, it would be hard to unintentionally add it to the trainable list of stats/skills I suppose. But I'm not sure whether or not it was intended to go live with the last content release, as it was not in the patch notes.
