I think part of the problem with this line of thinking is that it would literally auto-cap new jobs for anyone who bothered to raise the original class unless you are suggesting the split have it's own independent level? D: one issue I always had imagining new soulstones for existing classes back when it was still a possibility was the thought of never getting to "level" the new job if I had already done a previous one tied to the same class. SMN/SCH, while convenient, just felt off in that regard to me honestly.
