Uhh that was many years ago. Played Diablo with some friends LAN, then played Median with some friends LAN, 2 of them kept dying to witches in A2 start area, we had a very hard time doing LC2 ^^ since my friend read it wrong - we tried Tfauzt then stopped. One friend kept playing and some weeks later we talked, he had killed dest Baal. So I played it with him LAN. We did so once every year but we often stopped mid way.
Once you have done all ubers within one ladder you should be able to replicate that within a week.
