I'm not saying it was 100% straightforward that CNJ was WHM and THM was BLM. I agree that CNJ having the nukes could have confused people and made it look like it could go either way. I guess my thought was that CNJ wouldn't have been able to solo without having the nukes and that's why they had it, but otherwise the spells were overwhelmingly WHM-like. It is odd for BLM to not have elemental nukes natively.

THM reminds me more of SCH really, with the mix of a few WHM spells, Dia, Banish, Resurrect, Sacrifice, but the other spells where mainly enfeebling / dark spells, making it the more obvious guess for BLM.
