Yes you would always use the dot on anything that's going to live for a fair chunk of it. Sen is a resource. 1 sen is effectively 20 kenki. Higanbana is 940 potency for 20 kenki which is crazy efficient. Kaiten'd Midare is effectively 80 kenki for 1080 which is pretty overpriced for what it is.

Confused why people are looking to add Enbi to their basic rotation. The value of Yaten and Gyoten is the ability to maintain dps uptime, not procing an attack that will do about 70 more potency for nearly 3 times the cost, nevermind that yaten and gyoten themselves are kenki inefficient in terms of damage dealt. Plus however many auto's you miss.

Like, they're good skills for dodging AE and getting back in there and maintaining some semblance of dps when you otherwise would be dealing none, but as part of a standard opener or something you'd want to be doing on cooldown? Even on fights where the tp cost wouldn't be an issue, I don't see it.
