I have a bunch, but I'll just post one of them today.
I was pretty bored, so I was running around The Barrens. On any server, it's pretty much invariably true that a bored level 60 with World Defense turned on will fly to the location you're attacking, track you down and kill you. This was no exception.
I was fighting the guards on the border between Ashenvale and The Barrens. Right as I killed my current target (these things were cake. They didn't even touch me), a level 60 Rogue ran past me. As I looked around, I noticed he dismounted and stealthed. I quickly stealthed, turned perception on and walked in his general direciton.
Of course I underestimated the potency of level 60 stealth. I quickly found myself cheap shotted and at half health. I gouged him, vanished and ran away. He didn't kill me!
Then, I went to Crossroads and started killing some guards. The same Rogue ran past me just as I killed a guard. He didn't stop right when he saw me, but he did turn back while on his mount. I had already vanished, and I was waiting for him to come find me. He stood there as he must have been trying to do something for a few seconds. I sapped him, gave him a hug and sprinted away. He didn't kill me again!
I waited for a few mintues for him to find something better to do. It worked! I didn't see him again. However, as I was killing another guard, I noticed a ?? (at 49 that means 60) hunter in the distance. Right after I killed the guard, I stealthed. Too bad hunters have "Track Stealth."
He found me, put his mark on me and started to kill me. Haha, what a loser. I turned on Evasion, ran towards him ALMOST KILLED HIM (got him down to 2%) and he USED A POTION.
I got him down to 8% again before he killed me.
