I had a similar experience to Cedric, though I got up to the end of the second tier before deciding to pack it in. Now, I did do quests, but I also did a lot of scenarios and open RvR, in the basins, so I figured I was seeing what the developers wanted me to see. Honestly, I didn't enjoy it that much. Some of the scenarios were cute, but they had very little variety to them and so using them to level was incredibly boring. The RvR basins were an interesting idea, but most of the time it devolved into waiting for a wargroup to form and trying to take a keep, which involved a lot of waiting around and a lot of trying to direct people to take capture points (again, waiting around) instead of just charging straight for the keep and getting slaughtered. Adding to that was how useless the buff low-level players in a tier would get, the lackluster public quest system, the "achievements" system which involved grinding against a massive amount of identical mobs, which even WoW doesn't fall for (and to my horror, LOTRO does), the poor discoverability of the battle system (a trait WoW shares) and the worthlessness of the game when no-one else was around, and it didn't seem like fun times.

There were things that WAR did right - the chief one that impressed me was how PvE abilities worked more or less the same in RvR, including things like taunts and crowd control, in ways that encouraged enemy players to act the same way mobs would. But overall it wasn't the step up above WoW that I wanted.

What baffles me is why there isn't anyone who's decided that the secret to WoW's success was that it did PvE far better than its competitors with a shiny coat of cartoon paint, and try to one-up Blizzard on that score? There's lots of people who like the idea of MMOs but are horrified at how much repetition is required to get anywhere in a genre that prides itself on its massive, everchanging worlds.
