It's time to redesign Level Sync

[Sayora]

Level 20 Lancer can raise their damage 15%. Can not do any aoe damage at all.
Level 20 (70) Dragoon can raise their damage 15%, can increase the target's piercing damage taken 5%, can periodically raise their damage a further 15%, has a dot, can raise the party's crit rate, can raise their damage yet another 10% while raising another player's damage up 5%, has multiple aoe attacks.
There is no reasonable way to make these players even remotely similar in dungeons.

Tanks would be huge too, GLA with no RoH versus a PLD with RoH. Being a job when low level already gives you an edge too with stats.
