Lore in my opinion is by far one of the biggest pain in the butt skills to learn. I say this because usaully the people who need it are warrior's with low mana and no trance. I think lore should also increase based on the number of hours you have into the character. A warrior who has walked the lands for 200 years should have a little more knowledge than the warrior who has been around 25. The wisdom of the character could also affect the gains. Just my idea for the day.
