Make a small change that would break a class completely.

[Raminax]

I don't think anyone truly understands what 'break' means, either. Or that the term 'class' was specifically mentioned instead of 'Job'. I think I've been pretty spot on with my ideas.

Well, even in the OP's case, they use a Job exclusive spell...

On topic:

Life Surge is no longer consumed by the next skill used. 15 seconds of guaranteed crits, woo!
Esuna/Leeches no longer have any restrictions on which debuffs can be removed.
Aetherflow stacks are now infinite, eternal, imperishable, endless.

Yeah I dunno D:
