I still love the Ebon Blade daily quests. Every kid I level ends up exaulted with them.
I also like the cooking/fishing dailies in Dalaran and Stormwind/Darnassus.
I don't really enjoy the Iron Forge ones as much.

I do not like Therazane or Wildhammer dailies. Therazane in particular annoys me because every alt must do them.

I burned out on the Molten Front (ha!), but I can see that after more time passes those dailies might be fun for alts to do.
I have just recently started doing the Argent Tournament dailies myself...and they are (so far anyway) on my do not like list.
Mostly because I loathe jousting from the depths of my soul.

Ravyn: Jousting is easy peasy. Do jump-turns, throw the shield-breaker when they're moving away, and then charge. Don't let them charge. Keep your shields up.

Back when I did the AT dailies regularly, the jousting ones went smoothly and quickly for me.

"Therazane in particular annoys me because every alt must do them."


This faction is pretty much what has completely killed my desire to seriously play alts this expansion. Twice through Deepholm was about all I could stand.

I do the tournament quests when I'm bored. I figure the pets will be worth a fortune once pet battles get here. Hint: Even if you are going for rep, pick the cash reward because it also contains a mark. You'll be maxed out on rep quick enough.

At exalted rep with the main five home racial factions and with the Argent Crusade, I was doing 9 quests. 6 from within the Argent Tent (two guys by the quartermaster, four quests from the three in the corner), then from the faction tent there's three quests from the Sunreavers/Silver Covenant. If you're getting the bag of goodies with all of your turn ins from the Argent fellows, you'll be getting 12 badges a day, which sets a nice pace for the mounts and pets that I think they dropped the ball on when it came to the Molten Front.

As for other rep grinds, take a look at the BC reps if you're not concerned with the gear from the Cata reps, which it doesn't sound like you really are. Netherwing is a long haul but so worth it for the drakes (you get one of them free at the end when you reach exalted and then can buy the rest) and I personally found the dailies kind of enjoyable. Except the skinning daily. Blegh. Cenarian rep gets the first hippogryph that was available in game, and can be done with turnins and dungeon runs, and can do Sporegar alongside of that...the minipet you get from Sporegar is adorable as hell. I haven't yet gotten to do Sha'tar Skyguard dailies/grind for the Netheray mounts, but doing that helps with some Orgri'la dailes (and Christmas achievements). The Shattered Sun Offensive can net you a title at the end and some nice looking gear, those dailies are much less of a pain without others doing them. The faction grind in Nagrand for Talbuks is doable fairly fast, no dailies associated with them, though. Scyers/Aldor is irritating, but is a dungeon grind like the rest of the group reps in Outland.

If you're looking for mounts, I'd do Netherdrake next, then the Sha'tar, with Tol'Barad mixed in for the two mounts and minipet there. From there you've mostly got rep dailies for SSO, Orgri'la and dungeon/repeatable quest/turnin grind for the rest of the BC factions, Canarian Expedition and Nagrand faction nets you the most mounts out of the grinds . (There may be a daily for the Etherials, but I think they're a grind through dungeons too)

Wrath reps, Wyrmrest gets you a mount with their one piddly daily grind. The 'Big Blue Ladies' of the Storm Peaks (accessible dailies after you get to the Sons of Hodir) have a chance for a mount out of a bag drop, and the Sons of Hodir have two mammoths you can buy with high rep for their dailies. I personally can't stand the sexual innuendo of the SoH, so I turned in Relics of Ulduar and was done with them (and since they were for the shoulder back then, it was worth doing, and the BoAness of it wasn't freakin broken like Therazane). The Kalu'ak get a nice fishing pole and a minipet for their dailies, and if you're going to dive into Sholozar for a mount, my suggestion is to do the Frenzyheart (the tanuki) to exalted for the achievement, then do the Oracles to be able to buy the egg that gives you a shot at the green protodrake and a handful of minipets. (Like Aldor/Scryers, you'll lose rep with the other faction when you work on the one set) Im not sure how doable Wintergrasp things are now, would make a point to do Tol Barad before the end of the expansion so it doesn't suffer the same fate as Wintergrasp and Haala and become nigh impossible to complete after the expansion passes.

What one of all of that was my favorite? I probably enjoyed SSO the most for how well laid out it all was. Also, when I did SSO rep, I didn't do the quests that took you back to Outland, just did the ones that were on the island, made it easier overall and left room for some others. And yes, Im an altoholic and did a lot of mount/minipet gathering. XD

Also; the fishing dailies have a chance to drop a minipet out of the bags (even the Org/SW daily), Dalaran has a chance for a nice rare fishing pole, and the Outland has a chance for a minipet depending on the daily and some decent junk/stuff out of the bag otherwise.

And a note on the jousting; you can throw a shield breaker and charge in very rapid succession, wail on 2 and 3 quickly one after the other and you'll do them both super fast, wheeling around and doing it again makes for fast jousting. Just be a bit careful and mindful of where you are when you're doing the commanders out by the citadel.
