A "meh" experience until you get to raiding that is....
The only good thing in WoW, in my opinion is the raiding. During the majority of the game you're simply wasting time trying to level at get to 60; fair enough. And that's the only reason why you feel like you're playing this game, to get to the max level.
At level 60, the game gets a whole lot better with raiding. That is, it "was" better until the expansion came out at which point your whole aim is to get to 70. Sadly, once you get to 70 there is no rewards. The raiding is terrible and mediocre and that's basically the only thing you can do at the level.
So since the expansion was introduced, WoW has been converted into a meaningless game. You basically play to level to 70, and...that's it.
WoW, what a waste of time that was. World of Warcraft was a good game, but if you're into heavy grinding again and again and again doing instances again and again and again, and levelling again and again and again then you should get this game.
If you're looking for a brilliant end-game experience...then sorry you've missed out on it, there's no such thing anymore in WoW.
