WTFspaghetti has a map of the new argent tournament daily quests. In addition to these dailies, the patch introduces a new random-location fishing daily quest which sends players to one of five locations (some of which are relatively far afield), and makes one of the Wintergrasp dailies substantially easier to do on off-hours (NPC guards now count for the "kill players" quest). Adding these onto the map can make the daily quest travel route span literally the entire map.
Realistically, solo daily quest content is not going to be very challenging unless it relies on something like the vehicle system that gives the devs absolute certainty as to players abilities and damage potential. With the sheer range of classes, abilities, and specs, content that pushes the best solo specs to the limit would be impossible for others. So, we get mounted jousting and we get dailies where the challenge is external to the actual task at hand - the Wintergrasp quests present the possibility that you will encounter and have to fight the enemy, while the others fill out the time by making you travel across the world.
The latter is frustrating and lazy design. Unless you're stuck waiting for a respawn when you arrive, the time it takes to travel to the locations of most of the new dailies significantly outweighs the time you'll spend there once you arrive. There's no challenge, thought, or entertainment anywhere in the process; the devs have simply decided that each quest should take a certain amount of time, and placed the quest objectives accordingly.
For example, one mob literally involves flying across two zones, killing a single nonelite mob, flying across two more to use the quest item, and then flying (or teleporting part of the way, for mages and owners of the Dalaran hearth rings) all the way back to the start. Seriously, they might as well have frozen my character in a block of ice for 10-15 minutes and awarded the quest complete for all the interaction the quest requires on my part.
Overall, some of the content is still well done, but it is very disappointing to see "watch your character fly places" play such a major role in the content pacing.
