So far, I have uploaded almost all of the dungeons boss battle. it is not the whole dungeon run, but you could guess the difficulty from boss battle.

Story and instance dungeon boss battle all

(I only record full cut-scene and boss battle only, else the video would be too long)

For the OP question though. Yes, it does getting harder and harder. I could notice the different while stepping up the stone. Especially level 40-50 ones are all quite intense in the fight.

Note: I will always start my video name with "[FF14AR]" so if you plan to watch any update, then you can search youtube using that keyword. I plan to record all the available dungeon and important boss battle such as primal.

Note-2: I just added the latest story scene video, because the Ultima Weapon is too interesting.
