Level 4 Limit breaks?

How about let Black Mages cast Ultima

Only if we can somehow graft the Heart of Sabik into our staff.

I'd much prefer we have a big damn spell we can only use sparingly that does not rely on LB but rather requires a 15 second cast time. Maybe in a expansion perhaps. Something to accentuate the raw power of a BLM even moreso then Fire 4.
