Horntail Seduce?

Bolded because it might be significant.
When I run, it's with a sed mule (pally who does no attacking) and my buddy. We always enter in the order: pally, my buddy, and I. When seduce jumps at random, it always goes to my buddy, who does more damage than I do.
Might it be that HT has gotten "smart" enough to seduce the person causing it the most pain?
When seduce jump

Interesting theory, but I don't think she could out-do the DPS of a 17x Night Lord :/ This is quite annoying, especially for runs that really need all the damage we can get, we're only just starting to boss and losing a big chunk of our damage output hurt the time quite a lot.

Thanks a lot for the help guys, but its looking like it is just random and that there isn't any way to determine who will be sed beforehand. If you've got any more ideas, feel free to fire away, but I can't think of anything else. At least I don't have to be a sed mule all the time I guess.
