I'm running the exact same set. Found that swapping the attack speed passive for the near death experience and the cool down passive for the dodge chance one helped me a lot.My monk is up to GR69 now but I cant for the life of me complete a GR70! Its like a wall that Ive hit and just cant beat. Im running a Shenlong/6-pc Inna/2-pc Rainment build with really good gear, even mostly ancients now too, yet my damage and survivability just arent enough to break GR70, even after running it a couple of times hoping for an easier map roll. I kill just a tad too slowly yet, and tack on a few deaths and the timer gets me every time
The biggest weak spot is my legendary gems, they are 50/38/31 right now. I seem to have outpaced my gem leveling so maybe I just need to level them up and Ill accumulate enough damage to push me over
Also I swapped out breath of life for blinding flash with the 25% damage reduction rune.
