Notes should have zero level restrictions... Period.
What's the point of high level notes having a level requirement of 35? All it does is arbitrarily slow down high level crafters.
All notes should have a crafting requirement of level 0, so non-crafters can make notes for crafters. That way, non-crafters still have something to spend their labor hours on without having to worry about the 1 whole xp you get from a note, and the high level crafters don't have to worry about wasting a whole day's worth of labor just on notes that don't give any damn xp for their time sink.
