I remember back in Vanilla before you could turn off XP...hanging around outside of Org and dueling was about all you could do. But then one day, one of the guys in my guild figured out you could die, spirit run all the way up to Felwood and collect Timbermaw rep by begging anyone you saw up there to allow a dead lvl 1 into their party. You'd then have to go back to Org, rez at the spirit healer, have a Warlock summon you RIGHT ON TOP of the rep vendor, and then hearth back...all with 35 XP to spare before level 2
I accidentally discovered areas and dinged on more than one twink...
