Okay here's my educated idea on the topic of Warcraft lore Arthas AKA "The ((Former)) Lich King" seems like the biggest and baddest villain to a lot of players of World of Warcraft because he was in Warcraft3 in fact during the Blizzcon some Friends of mine were saying that Deathwing was just someone Blizz made up recently to keep WoW going. I srly went /facepalm and those who played the Warcrafts before W3 would know what I'm talking about. If Blizz was to make a W4 that would allow more flexibility in the storyline and allow the player base to remember who the real bad guys are....the KKK members that spawn in Lady Deathwhispers Room in Phrase 2 :P
