BLU party content is challenge content. If you want to do, .e.g., Alexander Savage with BLU, everyone should
1) already know the fight, as executed by a standard job party composition
and
2a) know how to handle the fight as a BLU party
or 2b) be prepared to wipe and then get it right the next time
People shouldn't be doing those fights on BLU if they can't already survive them as a real job. Do the learning on a different job, then apply the knowledge to BLU. Accordingly, raise is not something you should need or rely on in a BLU party.
