Got lucky on this route today. Andariel visage legendary and Natalya helm set item in one run Considering my gear, lady luck and godess of RNG have smiled on me. Getting lots of 3 rares per elite (not killing them in one blow).
As for the Warden and Butcher, It's a good addition but consumes more time (will ad it after I gear up so I can kill them fast). I don't open game for public because it lowers the MF.
I don't know how it is for other chars, but my barb just pops Wrath of The Berserker and kills butcher in a little over a minute, totally worth it timewise, in contrast to the argument regarding the first 5 elites each run. Am I missing something here? I don't change to MF gear or have any on me, so does that make the difference between 20 mins runs and 1 hour runs?
I don't have high MF stuff so I don't switch (my 75% MF + NV gets me to 150%). Get 2 rares per elite pack in general (sometimes 4, but average is 2). 1 hour run gets you more rares per run, but I concluded that my luck changes with every new game, so more runs per hour gets me better chances (superstition I know) :). As I wrote, found one legendary and one set item in single run. One before that had lowest elite spawn I have ever seen in act 1 and had all crap gear.
