Fighting in higher level areas yields slightly, but not noticeably better XP. Although the true benefit lies in the fact that in the higher level zones resources drop more abundantly, or with a higher chance.

In actualy fact, if you're just looking to farm affinity, the best bet is to just rinse the raid or defense mission in Mercury, simply because the xp isn't too much different and the mobs are laughably easy past a certain point. Hopefully they will fix this later in the closed beta.
