Okay, so OP isn't even 50 yet.

At 50, the game literally falls over itself trying to give you EXP, but even before 50 you have the beast tribe dailies, hunting logs, FATEs, multiple side quests, not to mention levelling roulette which actually gives increased EXP because, well, the clue is in the name.

It got to the point where I was constantly switching jobs because I didn't want EXP to go to waste.

OP, you have barely scratched the surface of the game and your original post smacks of ignorance - although I will give you the benefit of the doubt and be of the opinion your ignorance is just because you actually did not know, rather than wilful ignorance.

Keep going, you'll soon see...
