I'm pretty sure they do, but it's not very good if I recall. You should do dailies to get gold, not to level.

Actually Pimpy, in the xpac with leveling dailies, you want them for the xp. Once you get to dalaran you can pick up the daily cooking quest (mats easily obtainable at low levels) and any production daily quests available to you, and there are about 6 dailies spread between Borean Tundra, Dragonblight and Howling Fjord.

Right now (at level 77) I can do 9 dailies each day for about 200,000 xp, which helps a lot when you are looking at 1.6 million xp per level.

On the cash side, they only grant about 4-5g each, so do them for the xp, not the gold.

Well, I look like an idiot.

But once you hit level 80, the 20,000xp will be converted into gold. I'm hearing an average of 15g-28g for some dailies at level 80.

But yeah, considering you can repeat them over and over, I'll be doing dailies to level wherever possible. It only means more quests to finish at level 80, which means more gold from xp conversions :)
