for the longest time i did MP0/1/2, depending on current patch, and did Skycrown battlements, Keeps 3/2, Tower of the damned 1, rakkis, and fields of slaughter.
But the run was too long, so i cut it down and did that for a while. then i said screw it, at about Plvl 60ish i started doing only Keeps 2 or Scorpion runs in Arreat crater 2. did that till i hit 80 and from then on i only did scorpions.
Needless to say i welcome the density changes coming with the new patch. Working on my barb and wiz now. Waiting to do the barb for the new patch, where i will try to do the barb in a week or two, live on stream.
The wiz will happen as it happens i guess. My side project is to figure out a way to run MP10 with Tempest Rush. It is possible, just gotta find the right gear i think.
