missions

Hi,
I was wondering if the mission rewards increase as you go further into the game. In the beginning, you get a maximum of 2k xp. (not icluding killed monsters). But if I get further into the game, does the xp increase from 1000 to 2000 for mission/bonus (or change AT ALL) for mission/bonus?

the exp. rewards stay the same, exactly the same. and most of the missions get harder.

Also, the bonuses get much much harder to unlock... some of them are really tricky.
