Starting back up

Also, I remember there used to be a sweet spot for doing ancients where you'd get more levels. Did they take that out? I couldn't find anything about it with Google.

As far as I know, you only get 1 level, regardless of what level you do it at. I think that's how it has always been.

I think there is a level "requirement" that you have to meet to even do the ancients, though. 20 for normal, 40 for nightmare, 60 for hell, if I remember right.
