Just a thought, maybe it was never the aggro it was generating that made the mobs stick to you... but in fact the blindness that it caused?

Maybe it's the blind portion of the spell that's broken? Blind mobs will run away unless there is somebody within reach. If there is somebody within reach they stick to that player.

Anyway, just a thought. Not having flash of light, I have never tested tested it on this server.

I messed around with the Enchanter blindness spell a bit when I first got it and it seemed to get mobs to stick to my pet but it also wore off very quickly which is why I didn't bother to keep it in my spell bar (spell was too situational at best).
