Sorry, by your wording it seemed you had been complaining about the healer, not the tank. ((Edited due to being unable to read, apparently))
Your story would have made more sense not mentioned the healer in the same set of points as the tank you were complaining about.
Edit, glancing at what I originally quoted, I edited it down to that last line because that was the point I felt you were blaming the healer even more. That entire quoted sentence sounds like you were blaming the healer. I was wrong, apparently, but that is how I read it as.
