I can't speak for 4Ever's circumstances, but Nightmare is a good breakpoint for arenas for me because it's the highest difficulty I can one-shot miniboss rounds with decent consistency. So Nightmare for speed runs. BT if I have time. Though the time difference nowadays is fairly minor.
BINGO! had about a 1.5-2 hours and some other stuff to do and playing on this netbook is a little slow so it takes that long more or less.
I normally do the first page on BT and the 2nd page depends on how much time I have. But most of the time I never finish the 2nd page, I end up doing them right before the dawn and run out of time so I start Trio & Tree right at the dawn then finish it when I have time later.
Doing them on nightmare I can kill everything with WoT 99% of the time, using Chain on NM is close to 90-95% and whats left only have a sliver of life. So if I need to cast MM or hit the last monster with my staff (2 turns) Its just better to use WoT so each round only takes 1 turn, and I don't need to deal with spark going off all the time If I do them on battletoads I need to cast 2 tier 3 spells and a tier 1 or 2 spell to finish anything that's left. For me Its still faster to get Exp in IW.
