You don't need to spam RB that much. I typically RB a couple times on waves 2-4 each and one more time during the additional wave of adds in the middle of the 4 dolls. I only RB sparingly since as a monk I'm mainly responsible for burning priority adds fast. Doing RB every time there are still 3 or more adds up is overtaxing on tp. Save that for the ranged dps.
