So yeah, decided to do one myself, especially since I've done guides before (for games like Elsword and Sengoku Providence).
This is mainly focused on players of various levels of power, so it more or less points out noteworthy Eidolons that are worth using, even R and SR ones until you can get better ones... So it's not just focused on the best ones in the game (like the 100% ones), it's more focused on what you might have.
so tell me what you think. when more Eidolons come out, I'll add to this. Might be worth making changes you guys point out too.
