The addiction itself isn't the problem, the problem is the method (Which Blood Elves still cling to) hence why I said it as "magic siphoning addiction".
Blood Elves have gotten so used siphoning mana from living creatures that to many it's become a Blood Elf way of life and many people are addicted this partiuclar method and arcane magic and have remained almost indifferent to the Sunwell's reignition.
I'm not sure how I feel about people proclaiming Alleria as the new leader of the High Elves. It would be nice if she was a figure head to move the High Elves in the right direction and take a more proactive role in the Alliance. But she has never been this renowned leader of elves.
