For some reason, some mobs tunnel-vision on me. Barely half an hour ago, six other people and myself (on my ranger with sb/lb) are fighting a champion destroyer harpy. During the fight, the harpy starts coming exclusively for me even though my pet is down and I've stop attacking to avoid the harpy. The harpy kills me, I'm revived by another player; a few seconds later, the harpy kills me again and another player revives me. Now this is the part that bugs me; I've been watching the harpy the whole time during my revival and the moment I got back on my feet, the harpy comes straight at me again. I didn't even have a chance to attack, I've barely gotten back on my feet and the harpy kills me again while ignoring 5 other players attacking it(6 overall if you count the player who revived me) It was like the moment the soles of my character's boots touched the ground, the harpy did a full blown kamikaze charge at me.
Keep in mind that this happened while I was trying do stay out of melee range from the harpy and the last part happened when I was a good distance away from it (It essentially came halfway across the room to get me).
This has happened numerous times on numerous characters/professions; they don't stop until I'm dead. I've tried control abilities; attacking more, even stopping my attack completely but some of these mobs seem to have one mission in life and that's to keep me dead.
