Agreed.

Personal opinion-wise, I am against Oracles for the fact that many healers can easily heal your team when their BB/SBB/UBBs are used. Take Elimo for example. She heals a large amount of HP whenever you cast her BB/SBB/UBB. This, as a result, negates the need for increased REC.

Which totally beats the purpose of being an Oracle. Unless, however, said unit has BB/SBB effects that run on their REC. Otherwise, nope.

Guardians are different. Sure, losing a chunk of Atk sucks. But the good thing is you can still absorb a certain chunk of damage in return. At least they're still viable compared to Oracle, which is totally un-needed due to the healing rate of most recovery BB/SBB/UBBs.
