I used to hate the 50-60 climb. It was (obviously) the longest ten levels, and they were spent in some of my least favorite areas. Outland is MUCH improved over those levels, however. Lots of fun, original quests, much better itemization (you actually feel like you're getting cool stuff too, not just another stat point or two), and interesting areas. If you can force yourself to level 58, it'll probably pick up a lot. Though, actually, the 50-60 "grind" isn't nearly so bad anymore. Burning Steppes and Searing Gorge are both awesome. Swamp of sorrows has a couple of high points. Blasted lands has a pretty solid main chain, and is not the exercise in patience that it once was.
