If dps pull for me, I stand by the solution of "let them die." However, after they die I say in party chat "I'm sorry, you pulled the mobs, I thought you wanted to tank them. Next time wait for me to pull." That is how you properly teach them a lesson.

Same lesson applies to this, let the dps die and when they do say "next time give me a few seconds to get aggro before you go nuts."
