Starting WoW fresh with one of the new class's and new 1-60 experience will pass some time for you until one of the other MMO's come out. MMO's are like cola, WoW is Coca Cola and Rift is Pepsi, alot more people drink coca cola but pepsi is still a worthy contender. There is no definitive MMO they all have strengths and weaknesses but WoW has blizzard, publicity and age behind it so obviously it will remain the dominant MMO for some time, That does not mean any other MMO is trash it just gives us a different flavor
