Listen up, teachers! Everyone knows not every action done by the WoW's NPC characters makes sense. This is your opportunity to change a moment in history for the better, by tweaking the situation to where they don't do something stupid.
Examples:
Anduin: Why didn't you kill me?
* Saurfang crushes Anduin under his boot *
Vol'jin: Ya be no warchief o' mine! You haven't earned my respect!
Garrosh: Then how would I earn your respect, Vol'jin? Thrall once earned the loyalty of all the races of the Horde. If I must do the same so that we may crush the Alliance under our heel, then so be it.
Vol'jin: Perhaps I misjudged ya, Garrosh. I tink ya be well on your way already. I'll ready my forces. Farewell,
warchief.
With all the criticism of BFA in particular I'm sure we can come up with some great ones, let's get this thread rolling!
