My favorite is the min/max of X/hr. My mage friend was always talking about best xp/hr while leveling and now it's best gold/hr while 80.

The funny part about it is he spent hours release night flying from place to place and doing math and testing on XP/hr and finally said over vent "Alright, I found the best place to get xp/hr at 70." I replied "good thing cause I dinged 71 waiting for you to figure it out!"
