meh i raided with the top oceanic guilds on wow, and its the most overrated thing ever... not only do u basically have to give up any sorta nightlife you have but you have to put up with some off the geekiest kids in the history of the world... and besides full time raiding sucks in the current wow, instances and raids have been newbidfied to make up for the lack of skill with current players.
before Ulduar came out (those that play know what im talking about) Hal, Benny and Myself used to do Naxx25, OS+3drake and H eoe in 3 hours... which basically means we did a full weak of raiding in 3 hrs.. was great free time after that
p.s Dont play it, its a life sucker and its get super boring if u dont like pvp and have more or less the best items.
