No. You can't have that.
When you are doing a lvl 30 Dungeon, you are basically doing it time-approppriate.
When this dungeon was opened to the Warror of Light, it was when he was Lvl 30.

You cannot have that because the Wwarrior of Light didn't have these skills yet.
People must understand that this game is FINAL FANTASY and Story is first unlike any other MMO.

Plus, there IS a setting that can help you get what you want, Unssynced Reviosinst Trivial Mode, or URTM.
