Rangers, Paladins, Shadowknights, and Bards all suffer a 40% exp penalty, which means it'll take 40% more exp to level than normal. Since it takes forever to level in this game to begin with, you may want to take the
class and race exp penalties into account when picking your character.
Rangers also don't really get good until later expansions, so playing one now is a challenge. They're outclassed in pretty much every role (dps, tank, puller .etc) by other classes. Here's a great thread on the class, though, if you're interested:
