Monk LOD WOL help

https://www.d3planner.com/960592814 here's my character rn

I'm stuck on GR 83 or so, my character is too squishy and runs out of mana too quick to do sustained damage. It's taking forever to get ancients, especially for stuff like Flavor of Time (expensive for blood shards) or Swamp Land Waders (had to roll them on a Witch Doctor). Are there any easy upgrades I'm missing?

Also, for survivability I want to take Near Death Experience, which other passive should I replace?
