We all know balance has little to no healing in TWW compared to other classes but I thought this was hilarious.
I have 4m hp and Rejuvenation heals for 128,000 over 12 seconds.
So to fully heal from 1hp with Rejuvenation alone would take 375 seconds or just over 6 minutes.
Passive out-of-combat healing appears to be 0.75% hp per second or 360,000 over 12 seconds.
So passive regen is roughly 3 times as strong as our heal-over-time ability that requires a talent point.
