There really isn't anything to do in game. Like people before me have said, some people like dailies, but most don't. While they didn't add many dailies, and the average raider most probably won't give a crap about operation shield wall (apart from getting to revered using the dailies). Outside of raids we are already back to cata. Pet battles could have been an amazing feature, and I did all the trainers up to northrend and got a little bored, sold my level 25 pets for 20k each and haven't really gone back to it since, it gets a little...tedious after a while. Challenge modes are basically your average 5 mans but harder, which we are forced to run everyday in order to cap valor anyway. They should have made some totally new dungeons, especially for challenge mode. Other small things like scenarios, which are useless dungeons you only do to cap the 15 a week for guild challenge.
Apart from that, and dailies, there really isn't much to do outside of raiding. I'm just glad we have 3 raids so it means most of my free time is spent raiding, would be nice to have something ingame to keep everyone occupied, and not grinding dailies or dungeons for cap.
Would really love to see something like a mount racing mini-game were you queue up for it, and placing 1st etc can unlock new mounts or pets. Something, original for an MMORPG.
