Aion

Hey guys i can get my hands on 2 CDkeys for aion for $20 each. Lot's of people have elaborated that people who play World Of Warcraft will not take a liking to Aion. I have heard many thing about Aion some say the end game content is "Broken" other words meaning no good. Other comment that the PvP is great. So i am wondering what you guys would think? I have quite a history of raiding during my time of playing World of Warcraft most of "The Burning Crusade" expansion pack raids i completed Kara, Black Temple, Grulls etc.. In Wrath of the Lich King i completed all new content as they were released in the patches; 10/25 Nax, 10/25 The Obsidian Sanctum 3 drakes up, 10/25 Malygos, 10/25 ToC, 10m ToGc, 10/25 Uldar including Yogg, 12/12 10m ICC, 11/12 25M Icc, 6/12 HM 25 ICC
