They don't like the story so they rewrite it and pretend it's 'true.' They say to themselves "I don't like that" so they change it, in their minds, and accomplish nothing more than delaying the process of accepting the world for what it is.
As you might have picked up from previous posts, I'm not too happy with the revamp of Onyxia. It is a loss of historical evidence. But that is survivable, just as Naxx was. I could even accept that it is just a little area that isn't of the world. It's not lorelol or whatever, it's just not lore. It's the equivalent of the LFG channel (how are we throwing our voices around the world, especially those of us who possess no magical ability?), strange if you stare at it too long, but hardly game-breaking, and beneficial overall.
But we turn in her head. I don't care that we already did. That's the old time travel thing. No problem. But Varian chopper her head off already. If there was no quest, then Onyxia would be almost entirely separate from the rest of the world. But she isn't.
So I wrote my own lore. Onyxia was reborn by Deathwing, twice. Once when we first removed her head. Then again after Varian did the same. So this is the third Onyxia. Everything is perfectly consistent and logical and all great except that it isn't at all true, it's just BS I made up in my head.
This leaves me with a question: Do you rewrite the lore in your mind so it makes sense or are you able to accept it and go on with your WoWday?
