why the devs take the lazy way out on low lvl content scaling?

It would also be fun for newcomers to get an impression of the skills and spells they might acquire once they reach higher levels.

This isn't what would happen at all, what would happen is that the newcomer would just watch a level 90 SMN blast Denn the Orcatoothed with Akh Morn+Deathflare, end the fight in 3 seconds, because even with sync'd down stats you aren't meant to have a 1300 pot attack at that level, and feel like they didn't get to play the game at all, it sure is something fancy to look at but being carried isn't always fun.
