I don't understand how someone could say 375% or more MF is a waste, when what we are doing is farming for loot. If you are botting for loot, you should max your MF. Common sense. RNG is RNG, but I have had far better results after maxing my MF. I was one of the people in threads like this saying "I don't understand how you guys are getting those drops", so you shouldn't be telling people it doesn't make much of a difference - it does.
You can get 300% Base MF, plus your follower, plus your 5 stacks of NV, for a total of over 400%. I'm running @ 396% atm.
