Let’s say that when the draenei were first created retconned I actually really liked their lore. How they were the premier light Naaru revering race above all other races, above even the simp humans. So I made a Draenei paladin and crusaded for the light forever more… only to have the Lightforge come along and be more lightier than me… How am I supposed to feel about that?
It’s like introducing Elune-touched Night elves… They’re like Night elves, but blessed by Elune. Which makes regular Night elves what…?
Or introducing Greedlins, they’re like goblins, but greedy, making regular goblins… something not greedy.
Edit: Or better yet… Goldlins! They’re like goblins but their level of greed has taken them as far as fusing their bodies with gold, so that now they’re half golem-construct half goblin. Gotta have a foil to the mechagnomes right? And the Goldlins can even be paladins too! because shiny makes light!
