And what about Diablo, where on Hell difficulty, on the 3rd week, he accumulated 2+ hours of timer? Let's play Hell difficulty with 2+1+0.5. What does this have to do with a single game between players who are often short on time? The point is that Chaos Mode, especially in difficult scenarios on weeks 1 and 2, takes more time than Hell difficulty – you have to micromanage more in difficult battles, and the chains are at least as complex.
PS By the way, are you sure they were playing on that specific timer, or did they agree on some other timer? For example, like in Hell difficulty.
