AF quests had a good story behind them. COP had a good story, TOAU had a good story, zilarts story sucked but meh, WOTG had a good story. Rank10 missions had a decent story. All of this content was challenging, unlike WOWclone dungeons that aren't experts/heroics(and those are easy after you get gear FROM those dungeons ._.) BCNM's were unique boss fights. RSE wasn't anything special but it was another low level gear option and something for you to do besides leveling. Basically, at least it was different. I don't know about most people, but after playing WOW for 5+ years I don't feel like playing the same MMO until I die.
