Rift is a much more refined game than WoW is anymore. All blizzard is worried about is tweaking class mechanics for arenas and not making new dungeons and raids for end game. Lets see, cata hits with 3 raids, one of them being a whopping two boss raid, then they release firelands a few months back, and now the next patch will bring the last raid in, ALREADY. It just seems like they are putting WoW on the back burner for diablo 3, SC2: Heart of the Swarm, and Titan.
