Not so true..MF does help in getting the chance of higher afflixes. However, yes I think Act 2 is not that rewarding. I reduced farming Act 2 with 120base MF since I still get level 55 rares...Act 2 dying chance is so much higher compared with Act 1. I can run Act 1 with 245 base MF without dying (unless meet crap elites like Molten/Vortex/Wallers and IM).

Sure Act 1 still gives 99% crap but at least I dun have to pay for reapir fees. Only reason why I still farm Act 2 is that hoping for the crafting plans to drop whihc sadly...I only gotten 1 so far.
