Straight to the point: how do you feel about dungeons in Warlords of Draenor? Personally, I think they're solid bits of content -- most of the dungeons are fun, and in a video game, that's praise enough. My only exception to that is Grimrail Depot. I expected the zone to evoke the feeling of a wild west train heist more than it does, which might simply be due to the type of game it is. World of Warcraft won't ever feel the same as, for example, Call of Juarez Gunslinger. The dungeon never feels like you're anywhere but in the stationary depot portion of the dungeon until you fight Nitrogg Thundertower and the trials and tribulations of pickup groups through the dungeon finder saps some of the magic from that particular encounter. Beyond Grimrail Depot, though, I adore Warlords dungeons.
Unfortunately, I haven't been running them very much because they simply don't feel rewarding. The massive item pools means you have a hard time getting items you actually want. And now that LFR is open, you can get better gear more easily and nearly bunny hop heroic dungeons in their entirety. I'd like to see dungeons become more rewarding in this expansion. If not the loot inside of the dungeons, then perhaps giving you a shot at LFR-quality loot from a bag at the end of a dungeon each day. LFR loot is already so ubiquitous it feels like a why not? situation.
I also wonder if simply pulling the daily objective out of the dungeon finder pane and onto a daily questgiver in my garrison might make me feel differently. There's a lot of simple psychology at play in games -- seeing a blue exclamation mark right in my face might compel me to complete it and I'll probably have a good time doing it. Tucked away in the dungeon finder, I will never see it and never remember to queue for a dungeon from which I don't need loot, even if I'll have fun.
