Chupaman was either above or below me 1 level, I think he was grouped with Falius, but stayed back a bit at his healing totem while Falius went to pull. He had about 60-70% health and two totems up when I sapped him, removed the totems and then unleashed those 3 sweet crits on him for the kill. Then I re-hid and watched as Falius came back looking for whatever caused it. This was in SVT
I caught Steerhorn in SVT as well, he had 4 levels on me, but only 50% health and still just about killed me that fight. Later in the night he killed me 2 times with charge/hamstring spam, but I'm fairly certain he wouldn't have even had to do that. Whatever weapons warriors get cause a hell of a lot of damage.
Artera was another shaman in SVT, found her on the main road casting heals on herself around 75%, was 1 to 3 levels above me but didn't even attempt to fight, just continued running dropping earthbind totems until she died.
Serenas was a priest of some race that just got handled BB style. She was totally outnumbered and although I was the same level as her the warrior that charged her was quite a bit higher.
Aamoo was a Tauren of some sort that was involved in a 3 on 3 in Booty Bay, I took him down and then got handled myself by Fujak.
I've died quite a bit as well, especially to a priest. Jesus priests are hard on a rogue. All they really have to do is get off ShadowWordRape and then flash-heal until I'm dead. This guy flash healed 4 times, possibly more for 350-380ish. Totally negating my damage basically. I'm not sure who kills priests in PvP, but it's not me.
F priests...I've killed one priest on my Paladin, but I used a bomb and Hammer of Justice to stun him, plus he was undead. On my rogue, I usually just avoid 'em
