The only case I really think TCJ to apply TA makes sense is if TA has under 10s of CD, TCJ is ready and waiting for TA would result in a waste of Ninki :/
Otherwise, TCJ inside TA ftw on my case.

TCJ before TA is the best case scenario and will always be stronger than TA into TCJ. I pointed this out a ways back. Using TA prior to TCJ comes at the cost of using Suiton vs Raiton, or 180 potency. This is greater than the 156 potency gain TA yields during TCJ. Additionally, this saves you from severe GCD clipping from hard casting Suiton, and yields an additional ~3 seconds of TA vulnerability not wasted during TCJ.

However, we still need to be using TA and TCJ on cooldown, so this won't benefit us much in practice. Respective cooldowns of 60 and 100 seconds make it so we can't align them in this way throughout the rotation. But as Adelaide said, we should take advantage of TCJ into TA whenever possible. Why waste the free Suiton effect and give up a Raiton?
