The best way to farm chests is in a group and with p2p help. It's also convenient if everyone needs something different. What my group and I did was assigned everyone about three chests in an area, checked if they were there, and CRZ'd to a different realm. We cleared all chests in Hillsbrad on about 8 different realms in about 30-45 mins. One guy got feet of the lynx. I got my xmog stuff. Worked out pretty well.
