Although I refuse to do it myself, we all know SE is extremely slow when it comes to these things. Also, even though I am 100% against it.. XI was kind of the same way, In BCNM's you could reset shit by doing that same trick (Could be wrong here, correct me if I am. Played for 7 years but its been awhile) So I doubt SE will see it as exploiting. Perhaps they could change that fight to re-aggro upon group death. I don't know, but your post isn't the way to go about it.
