I get that Tomes should be rare drops, but keep in mind that players who have been at this long enough to surpass lvl 20 find themselves with trait points they cannot use because their traits are all above 4. Leveling up should always be a cause for celebration, but when you need to level 2 or 3 times at higher levels to actually advance traits or skills, it becomes less fun. So I think once you reach level 20, especially since it takes so much more XP to level up, the character should get 4 trait and 3 skill points per level.
And maybe there should be a point past level 20 when really tough rumor bosses or quests become available, things that lower level characters wouldn't encounter, which might have a better drop rate for things like tomes?
