Multibox leveling with RAF (48-60)

[Pyro-San]

Go to the hinterlands.

Multiboxing Mecca.

You will get 48-51 in about 3 hours.

I did this, from 48-51.6 in well under 4 hours.
Pick up all the kill quests, ignore the 'bring me back x of these' where x is more than 1.
Dinged to 49 while questing dinged to 51 within 5 minutes from handing in the first quest.
