Jan 13th 2007 5:25PM A) Nothing canon has ever talked about what it really means to be a Demon Hunter. According to the WoW site's encyclopedia:
"Illidan swore allegiance to the dark titan, who granted Illidan great power in return. Sargeras burned Illidan's eyes to ash and endowed the scorched eye sockets with magically enhanced sight. As further reward, Sargeras marked much of Illidan's body with an intricate pattern of tattoos that filled the night elf with powerful arcane energy."
B) Malfurion WAS the first druid. Again from the WoW site's encyclopedia:
"the first mortal druid on Azeroth was Archdruid Malfurion Stormrage."
C) The only error I saw in the actual article was concerning Malfurion seeking to destroy the Well of Eternity. That was never his intention, only to stop the Highborne and the Burning Legion, and close their portal.
