Wowpedia states that Lord of Clans takes place exclusively in the region of Lordaeron.
Last I checked, aren't most of the former inhabitants of Lordaeron part of the Horde?
And as I said, Centaurs only existed in Kalimdor and Dragon Isles, so it's impossible that they were enslaved by humans.
No? Arcane magic and Life magic are absolutely not the same thing. Arcane magic is what the Highborne used and it attracted Sargeras to Azeroth, thus starting the War of the Ancients in the first place. Life magic is the magic used by Malfurion and the druids and belongs to a completely different Cosmic field.Night elf embrace magic anyway?
We have an entire chart describing in detail how each magic force is different from one another, so you can't equate Arcane magic to Life magic.
The matter is simple. The decree is that Arcane magic was banned [since it was the cause of the War of the Ancients in the first place]. Dath'remar and co. defied the decree, so they were banished. It's simple.
The Burning of Teldrassil is, obviously, a far worse act than the banishment of Dath'remar, and I do hope you weren't trying to compare Malfurion's actions to Sylvanas'.It's not OK to burn the tree as it's not ok to nuke, enclave, exile people.
Regardless, Tyrande, Maiev, and the Kaldorei saved Kael'thas and the Blood elves from destruction at the hands of the Scourge. Thus, the Blood elves are no longer allowed to hold a grudge against the Night elves; because, without Tyrande and her forces, they would have all been slaughtered by the Scourge in Silverpine.
