pouncing's post is very good - I just was messing around and doing basically the same thing (I was excluding dancing edge because it was ST and I was sure a WAR or NIN was doing it elsewhere in the alliance), but using that priority list (probably not perfectly) I was #1 on the enmity list versus Xande against 4 other DPS in my group with i110 weapons including another NIN - I was i83 with i55 knives.

It works, I think we will need to wait and see if it is optimal, but it certainly is a very competitive dps strategy.
