The eternals and arcarum evokers have their own rating system separate from other characters. Ratings are taken from グランブルーファンタジーgamewithjp and should be discussed if any values should be changed.
Granblue Fantasy Jimmy Kudo Gamewith Wiki Tree Frame
Gamewith granblue tier list. Source edit edit source. Although they do seperate into more categories. Ratings are strictly taken from gamewith. Then again i cant read their write ups. Evaluation criteria edit edit source. Use other entries as examples on what to cover.
Each character has their own page at グランブルーファンタジーgamewithjp that you can take bullet points from but you dont have to strictly follow it. Evaluations for the top 5 ranked characters can be found on this page. Cag and vampy but the rest are still unchanged nevermind i became cross eyed. So many characters with wildly varying niches are all 8 9 etc. Some of these changes are already visible in the gbf tier list d. Although i still think gamewiths ratings are a bit too normalized to be useful.
This tier list is sourced from gamewithjps site. This is a very rough translation and piecing together of the evaluation criteria from this pagenote that this evaluation criteria is actually for ranking the top 5 strongest characters but can most. Also kinda feels weird to see the former powerhouses of vira and ferry falling down but powercreep and the shift of meta is strong. At the end of the day a tier list is just a tool to help you find useful characters. Amira is no longer stuck in the 85 meme. The reddit tier list also relies on the write ups to explain the tiers.
Tier list remarks and bullet points on gbfwiki are not necessarily from gamewith and are usually from wiki contributors.
