Is limit break not a thing?

In savage, the only tier you need Esuna is in O5S and you don't even need that if you're doing the train skip.

Wait, what? You can use Esuna there (I have not gone in as a healer, and things are so chaotic that I don't have a chance to pay attention to other party members bars, aside from which tank has prey if I'm tanking.
