Barbarian Setup

just came back to the game after Years and got a spintowin Barb. Clearing Torment 15 pretty easy. But how do I improve it, what is the best items to get.

Currently I got Full Wastes set and both Bul-kathos weapons. Some random Rings and necklace though.

You can check the stickies on this forum. Maxroll.gg has fun builds too.
