tbh I think we all just need practice. Was doing bismarck ex and maintaining near-100% enochian uptime by the second attempt. Fractal Continuum is pretty easy to turret on every boss. Neverreap can be a bit tricky, but if you don't have to carry all the mechanics then you can keep good uptime as well. I havent tried ravana ex, which admittedly is the one I think we'll be worst in, but people saying all the fights are designed to be impossible to maintain enochian in are just straight up wrong. We're weak in some fights and great in others, but even the bad fights we can do passably well.
I'd still like if they actually balanced casters instead of the eternal flip flop, but the sky isn't falling.
