Well lvl jump I'm not a fan of it but the content swap yes.
Glamor quest is lvl 58 because its ARR stuff and its kinda pretty lame for a noob altoholic like me. Beeing forced to be near level cap to use an apearance feature is kinda unic to FF XIV. Its not like if it was giving you any power. Some expension stuff could be unlockable prior lvl cap without creating any imbalance.
