The loot filter is very helpful but is still missing various features
These are
- drop sounds/map icons(the most important one in my opinion, as a lot of gear drops offscreen, especially with fast mono runner builds, DoT builds and big area builds - this means something good may drop and you may have no idea as there is no way to distinguish audibly between hidden gear drops and shown ones)
- a NOT rule, this is slightly less important, but often people craft onto gear that has at least one of their top tier affixes in addition to ANY of the still useful but lesser affixes, it may not be immediatly clear the difference between wanting to do this and a rule of SHOW ( 3 of top tier affix + lesser affixes) but if one of the non top tier affixes can take the slot of a top tier affix you may end up with 3 lesser affixes and not the one in specific you want, this gets especially troublesome later on when gear affixes need to be insanely specific and you need 2 or even 3 specific affixes on gear with one flex affix(at which point even with crafting being a thing you need a godly drop) - a hide (equip type)+NOT(the top tier affix) rule would solve the issue
The lack of a NOT rule in particular is quite troublesome, as if there are any class specific bases that appear in the future, that are specific to two or more classes, then the usual strategy of Hide(Primalist, Sentinel,Acolyte,Rogue) in order to only get mage and generic may break and result in not seeing a mage/acolyte base
