lol its not worth killing an elite to get 1 rare. with mf you get like 3-5 if the mf is high.
Yes it is very worth it. Especially after 1.0.3 where ilvl 63 items CAN drop in Inferno Act 1. Act 1 inferno is a breeze now for me. So getting a rare off of EVERY elite mob you kill after you have 5 stacks of NV is so worth it. You can kill them incredibly easy, get more drops, faster drops and even a chance it it being the highest ilvl in the game.
