I am once again begging for a rework on these Field Notes. A good number of them are fine or at least acceptable. But there are a handful of them which are criminally difficult to obtain and are antithetical to how Bozja should be engaged with in the first place.
Take, for example, a Field Note I only recently obtained: #43. It can be acquired through three different methods. The first and easiest is to sit by the Supersoldier Rising Fate spawn constantly, never moving because you run the risk of missing it if it pops. It took me 53 instances of this Fate before it finally dropped. Alternatively you can kill Magitek Rearguards in Z3 to spawn Hypertuned Havoc. You'll never know how many you actually need to kill to fill up that invisible trigger though so you'll pretty much be killing them nonstop until it triggers. This Fate chain will also lead to a Duel, but in order to qualify you have to beat the 'A Familiar Fate' Critical Engagement without being struck by a single AoE, a daunting task when you can only attempt it once every hour to an hour and a half. What's all the worse is even if every person attempting the CE is hit by an AoE it'll simply pick nobody for the Duel, not even giving the people or person with the fewest Vulnerability stacks the chance and resetting the entire chain.
In neither of the two prepatory methods of obtaining Note #43 are you at all encouraged to participate in other Fates, in Dalriada, or in other CEs. It bottlenecks you into strictly focusing on one hyper-specific method, with either option being either so challenging people rarely even complete the Duels without using cheese methods or it simply taking a tremendously long amount of time where all you do is camp a Fate spawn. It's not condusive to engagement with the whole of Bozja, only an incredibly tiny fragment.
And this is the case for many other notes, specifically the ones that require Fates to be triggered by killing specific mobs (eg. #14), ones you have to camp the spawns for (eg. #11), and ones that are either hybrids or otherwise demand completion of either Castrum or Dalriada.
And I want to repeat, most of the Field Notes are fine. They either are outright guaranteed, or simply have high drop rates or the Fates / CEs they drop from spawn regularly without needing to be triggered through kills. Many people will finish the Story content for Bozja and find themselves sitting on a hefty majority of the Field Notes. But for those remaining ones which are agonizoningly difficult to obtain, the only ones that come close to supporting engagement with the content are the ones that drop from Castrum and Dalriada.
Now, people have suggested the Field Notes be purchaseable, and I don't think that's a bad solution so long as it supports the running of the content. Currently the most difficult Field Notes don't provide significant life to Bozja given their specificity. Fortunately there's already a means to integrate their purchase extremely well, and that's through the drops Bozja gives. I refer specifically to Coins, Clusters, and Lockboxes. If Field Notes were to be made purchaseable as a solution I believe they should cost a combination of the various Coins attainable, a fair number of Clusters, as well as Lockboxes, since those require the completion of Fates and CEs and thus incentivize running as many as possible in both Southern Front and Zadnor. I can't speak to what the ratio should be, but I know that even if it was all exceptionally high it would still be vastly preferable to the current methods.
Another alternative would be to make the Field Notes tradeable. Personally, I don't think this is the best option, as it doesn't stimulate activity in Bozja like the prior suggestion. Only a few people would likely bother farming out the rarest ones and they'd sell at an extraordinary premium which people may struggle to afford or otherwise draw them away from Bozja to other Gil-making methods to afford them.
Another solution would be to increase the drop rates of Field Notes and/or the frequency of their correlated Fates/CEs. This would by far be the simplest method but again, doesn't factor in that engagement I spoke of, and that's fundamentally what I'd like to see. I don't just want the Field Notes be given freely but there are definitely ones that are excruciating to obtain and take away from other aspects not only in Bozja but in the entire game. Any improvement to their obtainment should facilitate engagement in all aspects of Bozja's content.
