As I've mentioned throughout my review, Battle for Azeroth's Azerite Armor has unfortunately ended up falling short of being a 'proper' replacement for tier sets, legendary items or even artifact weapon traits, let alone all three of them at the same time as was originally advertised. At the forefront of this problem is the simple fact that some of the generic traits are significantly more powerful than the class-specific ones, meaning that while each class technically has plenty of choices, a lot of those choices are actually a trap.
With that in mind, I am very glad to say that Blizzard has now issued a balance update in order to bring overperforming and underperforming traits into line. The list is relatively short, so here it is in full:
General
• Archive of the Titans: Primary stat bonus increased by 20%
• Laser Matrix: Damage reduced by 30%
• Thunderous Blast: Damage reduced by 35%
Death Knight
• (Frost) Frozen Tempest: Damage increased by 100%
Druid
• (Feral) Blood Mist: Damage increased by 125%
Hunter
• (Beast Mastery) Feeding Frenzy: Damage increased by 400%
• (Marksmanship) Arcane Flurry: Duration increased to 10 seconds, damage reduced by 45%
Mage
• (Arcane) Brain Storm: Duration increased to 30 seconds, Intellect bonus reduced by 75%
• (Fire) Firemind: Intellect bonus increased by 30%
Monk
• (Windwalker) Iron Fists: Required targets reduced to 3
• (Windwalker) Swift Roundhouse: Damage bonus reduced by 55%
Rogue
• (Assassination) Shrouded Suffocation: Damage bonus reduced by 40%
Shaman
• (Elemental/Enhancement) Natural Harmony: Secondary stat bonuses increased by 40%
Warlock
• (Affliction) Sudden Onset: Damage bonus reduced by 30%
• (Demonology) Demonic Meteor: Damage increased by 200%
• (Destruction) Flashpoint: Duration increased to 10 seconds, Haste bonus increased by 25%
Warrior
• (Fury) Simmering Rage: Damage increased by 35%
While I doubt this will make Azerite Armor any more popular, it should at least help make it a bit more balanced before Update 8.1 - Tides of Vengeance comes and adds a variety of new and supposedly quite interesting traits. Until then, I would highly recommend keeping your spare Azerite Armor around. I doubt it's going to get updated with the new traits, but there will definitely be a new round of balance changes in 8.1, so I'd say it's better to err on the side of caution and be prepared to change your traits around at a moment's notice.
