There should be other ways to obtain the Field notes.

I have to many Bozjan coins, I would trade them for notes. I don't need the coins. I'd trade all my coins for Lyon and Sartauvoir. I know the 1v1 is a guaranteed- but only if you complete it- and only if you're chosen when you get the prompt to duel. I've always accepted the Lyon fate duel- and never been chosen.
The drop rate of these is bad. It's not a fun map or zone to be in at any given time. I don't mind farming, but only if it's guaranteed after a certain extent. You could likely never get these note drops- Lyon and Sartauvoir are the only ones I've needed for months and nothing yet still.
