I think I made it pretty clear that I understand that the flaw is caused by the design of the game. You do not need to "explain" that to me. I was pointing out that it isn't unreasonable for people familiar with other MMOs to come to this one thinking that healers... heal. Because that is what they do in other MMOs. You said it was "completely absurd" for players to have some expectation like this, and I pointed out why it is not.
