The biggest problem with claiming these monsters is not every job has an instant form of claiming. For some people they only have the one job they can farm on, making it next to impossible for them to get any Fleece. Whilst that is more an issue with the balance of jobs rather than this individual item, it's an issue that wouldn't exist if there was more of them. I also just don't particularly like how Fleece is so hard to acquire for anyone. It shouldn't be. There is no other item at this equivalent level that is so hard to get hold of. Hell, even Crawler Cocoons are cheaper and easier to get than Fleece and Twinthread is used in all the high level job specific gears.
