well I spend at least 10 minutes per bot and I do this every 8 hours(if I dont then i fill up my stash and lose out on loot). I have 3 bots so this is anywhere between 1 to 1.5 hours a day just managing loot. if i had 5 or 6 bots id be looking at 2 or 3 hours.It doesn't take very long to deal with the gear collected, 10 minutes tops. Worst case, you're missing out on 50-100k per bot. The prospect of earning triple the amount seems worth the tradeoff.
I think someone needs to test with a 300gf set with 0 mf and a 300mf with 0gf. Its pretty obvious if you can get 300gf/mf then youre set, but that really doesnt tell us which is better
