I'm so sick of "Azeroth is saved.". Its so repetitive, does barely nothing to push the threat of the enemy or the story at all. These late big threats, The Lich King's scourge, Deathwing and his Twilight Hammer and the Iron Horde were all built up to be these big bad-asses to destroy everything only to be watered down and be fodder. Stop creating these "Super-man savior" heroes like Thrall and Illidan that were born to save the world from evil. Its cheesy and not fit for the theme of Warcraft. These villains are being served to us on a different plate with the same flavor.
Whatever threat is next in 8.0, let them win. I want them to kill off a mass amount of main characters. Legion was doing it right until Sargeras' little incident in Antorus' raid. .
