I've heard a couple of different things now - is the health of the adds the same on 10 as it is on 25, or not? I was under the impression that it was. I recall the frost guys on the third door had around 10mil health, was it the same in 25m?
Not to nitpick or derail the topic, but I have to agree with Drummerboy that you're oversimplifying it by saying you 3-shot it when you spent 20 attempts on it just because you were still learning it. You could just as easily argue that the first two "official" attempts you were still learning it then as well, or else you wouldn't have wiped on those - should've focused on this guy, shouldn't have stood here, etc. Otherwise I could kill the boss and exclaim "ohhh, that's how it's supposed to be done! Well then all those other attempts didn't really count since we obviously weren't doing something right, so we'll just say we one-shot this."
But that's just my opinion anyway, I'm sure someone will disagree with me.
