I continue to level my horde character. I'm only in my twenties so things may change later, but so far I haven't found myself without quests to do.
My mount and all the added flight paths have made it easy to move from area to area doing quests that are green and easy to solo.
I always happen to see players out questing, but just like me they are usually solo. Usually no one wants to group, so I'm glad I'm able to kill stuff on my own at a reasonable pace.
As I do these quests and mine nodes, I think to myself, this has *got* to be the last time I do this. But then I when Cataclysm is released I'll make a worgen or goblin and level through the changed landscapes. That's how they pull...you...back..in!
