Level Sync QoL: Keep Abilities Intact

[AdamFyi]

I think that having all your skills available while level synced is tad a bit too overpowered - especially when you have new players (tanks come to mind) in the same party with a capped BLM or WHM. SCH is a good example for this since the pre-30 dungeons were not designed with SCH in mind. Those faeries become gods. o_0
