Quest game. Leveling isn't hard anymore. You can, however, still grind if you'd like and get crafting mats and blue gear. There's still lots of dungeons to do, and you can grind those for XP and gear. With 4.0 coming out, leveling will be even easier. The main 'grind' of the game is gear, but its fun. :D
I'm pretty sure I did instances straight to level 60, but that's just me. in a few days new content(4.0) I'd suggest just join then, it more fun when you have people to talk to.
