I'm sure someone has posted on this before, but search isn't helping me out at all here .. My Pally just dinged 75, and my priest / 3xmage are 50% through lvl 74. I get almost 21,000xp per quest turn in, but am getting 550-620xp per mob kill. My team is a master at AOE mob grinding as my pally can round up seemingly unlimited mobs, and a hotkeynet mouse brodcast to my mages for 3x blizzard finishes the job fast.

Every group of 4-6 mobs will net me around 2400+ xp in less than a minute at lvl 75. The problem is that I can never find enough of them grouped together and have to usually take 1 or 2 at a time. Is there anywhere I can grind large groups and burn through some of this rested xp? The time to do collection quests is making the 20k turn in xp inefficient.

Anyone know of some good AOE grind spots?
