Interesting. However this build is 1 month old so I hope it won't be nerfed at 2.4 release... also, I might want to use WDs as a main team (for high level GRs). But we'll see.

Anyway the speed-farming builds have a flaw that I can't really solve, which is : legendaries appear with some second of delay in the mini-maps (I mean the maps from characters 2, 3 and 4) so by the time they pop I'll be far away. Unless of course Blizzard fixes the lag with 2.4, which I doubt...
