And that's completely okay. Overhealing does not generate additional threat over regular healing... 500 points of overhealing generates exactly the same amount of threat as 500 points of actual healing. So even if your heals occasionally overlap, you're generating the exact same amount of enmity you would have if the other healer hadn't sniped you.

Aside from the very beginning of a fight, or when adds have just spawned, healers should not be taking aggro. If they are, there is a major issue and it *isn't* related to game mechanics.
