Don't be surprised if you die to a tank buster either, they can't even figure out when those hit they are standing around while you dip 90% of your HP. I've seen that with helping A12S parties.
Someone will probably pop their head out and said they cleared A12S as 0-DPS healer, and yes that is possible. But they probably did it with echo and their party carrying quite a carrying load on their backs while making them see void puddles.
