Patch 2.3

[Yelgis]

I've played PTR and it will bring me back. If I multibox S4, I plan to do 4 Crusaders or 4 WW Barbs. With the CC changes classes with toughness will be more important if you want to do harder content. If you are just speed farming low to mid GR's or TX, Wizard or Monk would probably work too. Plan to stay far away from DH and WD this season as the new WD sets are trash unless they tweak them on PTR and the DH didn't really get anything new that would make them better for multiboxing.

With the Saders, I would run the new Hammer build (I've cleared GR 57 so far on PTR with one solo) and with the cube you can get the zodiac ring on them and keep up Akarat's, Steel Skin and Laws permanently with a modest 45-50% CDR. Cubed Hexing Pants also add a nice bit of damage to the spec. With 4 Laws the group buffing should be pretty good. I am thinking running the critical damage, armor bonus, wings of angel for sure and the 4th law I am still debating on. It will probably be either Promise of Faith (25% less damage from all non-Physical sources) or Decaying Strength (up to 60% dmg reduction debuff on mobs).I really like the Hammerdin set minus Fallen Sword (this skill really needs a shorter animation for me to want to use it).

Barbs would be able to run Wastes 6 with BK weapons. The only issue with barbs is that only Warcry really stacks so they don't benefit as much from party buffing as Saders do. They do get to keep up Ignore Pain Mob rule with only 33% CDR in round robin though, so that means a multibox team of barbs would be able to use a differnt belt than the one that increase IP duration.

Both the Barbs and the Saders should have good movement speed. Barbs will move faster because of WW and sprint if you want it and Saders will have Wings of Angels for 50% speed and the ability to walkthrough mobs.

The big issue I see with playing multi in season 4 is the need to pickup crafting mats. From my time on PTR death's breath seemed to be the most precious resource of them all. I was always short on them because all the cube recipes take them in multiples. In the past I would just pickup crafting mats occasionally because it wasn't worth swapping through all my characters each pack and I would only swap for legendaries. Now you will need to stop a lot more to pick them up.
