I enjoy Blizzard whenever Racial Abilities are updated, for Example Orc Blood Fury was updated to provide Intelligence for Casters, or Draenei Heroic Presence gives core stat after Hit Rating was removed from the Game. Here are Racial Candidates worth a 2023 Update:
-Lightforged Draenei Light’s Judgment. First of all it is undertuned, as with the new Talent System the relative power of other Abilities rose. Secondly it should be targetable on Allies to heal instead of damage, so it is becomes more attractive for Healers and Tanks.
-Nightborne Magical Affinity increases Magic Damage by 1% which is terribad. Useless for Healers and all Melee Classes have physical damage components, drastically reducing the value of this. Even if you play a Caster it is better to pick a Race with 1% Versatility for the same DPS increase, but also more heals and absorbs and reduced damage intake.
-Mechagnome Combat Analysis. Blizzard took several weeks after Shadowlands Launch to scale this from LV50 to LV60. Two months into Dragonflight it still does not scale to LV70.
Emergency Failsafe. Good ability but sadly it specifically kills you in PvP against Mindgames Priests. Because it triggers automatically, hope Blizzard can code an exception for Mindgames in particular.
-Void Elves Entropic Embrace. Good Ability, but needs extension to Pets.
-Pandaren Epicurean. First of all it gets outscaled by other racials. Why acquire 76 Stats temporary while well-fed with the most expensive Food when you can Pick Draenei for 113 Stats permanently plus a heal spell and Shadow Resist.
The Racial could just be 1% Extra Secondary Stat depending on your Food (Main Stat Food would increase your highest Secondary Stat by 1%). That way developers have less work scaling the Pandaren PvP food every Expansion.
Finally, sometimes you die and the buff is lost. Death is expected on Shamans who have balanced less survivability via self-resurrection and in Battlegrounds. It is just not feasibly to sit and eat food in RBGs.
-Human The Human Spirit. Scales multiplicatively so the game becomes pay to win for Min-Maxers. In the first tier secondary stats are low so players are incentivized to race-change into something else, while in the final tier we have an abundance of secondary stats and Human sims top damage for many Classes.
