Or the even nicer way:

"Hey guys, I noticed we were placing the death zone onto the healers by mistake. If we try and put them [here] and [here] (using waypoints) I think we should be able to handle this no problemo. We got this!"

What usually helps the most, and tends to result in people NOT getting up in arms is:

a) Not singling out by name (as you suggest) and
b) Offering, politely, the solution/general tips so you don't just sound like a complainer
