Trinkets are lightly tested, may have implementation errors.
No legendaries implemented, if you get one use it, its good, if you get two, go buy lotto tickets
Set bonuses unimplemented
The outlaw model can be very slow at times, be patient if it takes a few seconds to recalculate after you make a change.
Assassination model seems to use too much energy, shouldn't have a large impact on stat weights.
T30 Talents are not implemented
Fan of Knives rotations are not implemented
Poison Knives (non-agonizing effect) is not implemented
Model just doesn't work, don't use it.
No combo point loss is computed, this leads to somewhat higher results than are achievable in game and decreases the value of haste.
Use finishers during dance setting doesn't behave correctly with subterfuge, leave this option enabled with subterfuge rotations.
Weaponmaster does not give bonus cps, may be somewhat undervalued
Flickering Shadows (sprint trait) not implemented
Artifact data from the API is now implemented. It only supports the currently-equipped artifact, because that's all the data that Blizzard gives us. If you switch specs, your other artifact will be blank.
Most items should now be properly supported (except Mythic+ items, see below)
Selection of WF/TF item levels is now implemented for gear. Relic support is on deck.
Fixed lots and lots of bugs with relics and artifact loading in general. It should be much more robust now.
Timewalking items are not supported until Blizzard fixes the API data for them.
Trial of Valor items are not supported until they're available from the API.
