I got 5 legendaries yesterday, the first of which was an IK helm with 235 str on it. My buddy who I run with has probably gotten 1 for every 2 legendaries I find, and he has 100mf more than I do. PL 27, I have no MF on my gear at all. Killing lots of elites is the key, I just power through act 3 in about 45min-1hr on my WW barb.
