I think the raid content is great and the Raid finder/Normal/Hard mode structure works well since everyone gets what they need from it.
My issue with the game is the level up content, dungeons, dailies, and some of the other activities that are almost impossible to fail at so they just end up feeling more like chores than actual game content.
I think this is WoW's basic problem right now.
While the dailies don't bother me too much. The non-late game content has just not aged well.
And while they redid the old world, only a few areas really seem "better" to me (thousand needles). And unless you start as a goblin, worgen, or panda, you are going to have a worse starting zone experience.
