With Shadowlands coming soon, azerite will no longer be relevant – our website has always been (and will always be) designed for the current expansion’s content. That means going forward we’ll have full soulbind and conduit optimization as part of Best in Bags instead of azerite and essences.
It’s just too much work to maintain all of the mechanics for every expansion, and not many people worry about optimizing below max level/current content, so it would not be a good use of time/effort.
The pre-patches are always a bit awkward… it’s not really worth the effort to come up with in-depth gear rankings because they don’t last long enough and it would take half the pre-patch to come up with them, and the game is in a really unbalanced state anyway… that Blizzard tends to change often leading up to the next expansion.
The current azerite/essence recommendations that we show will stay up forever though, for anyone who wants to use them when leveling through BfA content. We felt that was a decent compromise – it’s not a full-on azerite/essence mathematical optimizer, but it’s actually maintainable and still useful.
