Ok so for now I'm playing my "old" team with 3x Meteor Wizards and a zDPs WD.

As for the 3 extra passives...

- Weapons : 3x Furnaces for the DPs, I don't know what can compete with that, and Utakapa-what's-its-name-again for the WD (zombie dogs absorbs life, and since I already summon zombie dogs every 2 seconds)...
- Jewelry : 4x Royal Grandeur. Of course.
- Armor : I hesitated but finaly I went for 4x Leoric. With that, I can still make almost half a level of XP from a level 50 GR (I'm in the early 700's), quite easy with the 2.3 extra passives.

Torment X Normal Rifts drop a lot of legandaries, GRs are very good for XP, Horadric stuff is boring but I need the components so...

Also, the lead character should equip the bracers that pops elites from pylons. I got packs of goblins twice this way, and I even got a portal from one of the packs. I don't know how much money each character got from goblin vault in Torment X, but that was a lot for sure
