Pretty much just get used to having to revert back to the 2.x rotation at a moment's notice if you have to move at all. A lot of the boss fights in Neverreap and Bismarck EX in particular can be hard to keep Enochian up for too long IMHO.

Its not that the new rotation isn't challenging, its just that its kind of exhausting. I wish Enochian wouldn't slowly decrease its maximum timer, makes it impossible to keep it going forever, which I guess might be the intent overall? Just try to keep it up for at least 20-30 seconds so you can repop it manually? Who knows.
