I would say WD in s7 would be SUPER EASY. I could get stash tab in 1 day if i wanted. You are given OP set on the plate.
Wastes Barb would be much harder as you need BK swords to play it properly, as well as skull grasp ring and some other gear to be able to push gr70 or whatever needed for stash tab..
I am gonna play crusader this season and take it slow and easy.. Like a scrub
