I don't know about quad kiting but when I am pulling 2 mobs and one is almost dead he never runs while the other is nearby. This goes for aviaks, orcs, bandits, you name it.

Maybe it has to do with your proximity to the specters? I know that's now supposed to have an impact since you have aggro, just trying to think of a reason why it would not be working the same way when you kite.

Of course mobs (as well as players) move slower when they are low on health so the specter that's closest to dying should be running slower than the other specs in the quad. That part would be normal.
