Damage wise lightning isn't the real maximum damage spec, exploding palm puts cyclone to shame and does FAR more damage. More work into this mechanic can lead to far more damage than typical builds with a spirit generator. It's possible to get up to about 3 seconds of downtime on Epiphany.
While this may be a functional build without spirit generator, I am pretty sure that traditional lightning builds will out damage it since you don't have to make sacrifices and sweeping wind does A LOT of damage. I also doubt this build is capable of spamming LTK on every mob without running out of spirit, even with all these spirit generating cooldowns and passives.
Did you even watch the video he provided? It's clear he CAN spam LTK constantly, with epiphany only having about 8-9 seconds of downtime means it's up 90% of the time leaving him spirit capped constantly and was easily clearing T3 solo.
This build definitely looks primising with the right gear set, so glad i have a ton of CDR gear from my normal speed run TR build gear lol.
