Does not seem to be updated. The crafted levels only go to 645 and the actual available are 678. With the advent of delves and the ability to get gilded crests, it is easier to get to these item levels without being mythic raiders. Are you planning to upgrade the guides to reflect level 678?
I’m not sure to what specifically you are referring, but for example, if you run the upgrade finder and set crafted level to “All”, it will include the current highest level of crafted item, which has a base item level of 662 and a max item level of 675 (if created at quality level 5). Same with Best in Slot or any of our standard item lists.
