I'm thinking you're on to something. I, personally, have been very unsuccessful making profits out of scroll botting overnight for the past few weeks (for the record, I have also been running Contract, but the only thing I really get are Tricky ESs and maybe one or two forces/sentinels) But at this rate, I'd probably consider myself remotely lucky if I can even manage to make more than 10mil from scrolls in ~8 hours.
