dailies. and more dailies. thats 95% of your non-raid content, essentially. I dont hate dailies, but there isnt much variety in terms of gameplay. what if blizzard incorporated elements found in other games: like say, dynamic events in gw2, or events where you can coordinate with other players without a group.
dailies have their place, but they are weak as far as content goes. when something is routine, it gets boring. it's the reason molten front gradually became a ghost town over time. and other daily areas before that.
basically, I think blizzard needs to innovate a little bit, or borrow some ideas, if they want to keep things fresh/interesting. cause more dailies, is not the solution to people being bored.
