Kill rares for chivies, but the drops are worthless. (unless this has changed in the last month or so) There is an add on you can get from Curse.com
called RareDar that will let you know when you are near a rare or near the location where one spawns.
I am 64.91 so the rares have good gear for me. Raredar is ok RareTracker is much better. But figuring out what they drop is harder, so figuring out
which one to kill is the problem. I just left Goboro Reef so I am using all lvl 59 and 60 SL gear.
