Some changes are fundamentally different (like how we didn't have a universal Knockback Prevention before Stormblood), but mostly the essence of the rotation is recreated.
The reason rotations feel lackluster at lower levels is mostly because they truncated or merged actions and abilities at lower levels that didn't add much to the rotation, were just fluff, or could have been merged all along. A good example is Shield Swipe on PLD, which was just a rare ability you'd press to do a little extra damage. Even when they've reworked some jobs, they've tried to preserve the core essence of what was done in those expansions, even if the abilities themselves have different effects (AST cards for example).
The drawback is that it's ultra confusing to do a roulette and have a wildly different rotation depending on the level range, or sometimes an incomplete rotation in leveling dungeons.
As a compromise, if they preserve your max level rotation when syncing down, they could have a setting that syncs the rotation down still in Duty Finder settings so that people doing old MINE content are still able recreate the experience from a prior expansion.
You're not alone in feeling this way. It's commonly brought up and has been for years (almost as long as the game has had expansions for). There are just drawbacks to it that will probably prevent it happening, like being overpowered compared to a new player. For now, the only thing I can suggest for people who do not like this is to simply avoid such roulettes and sync downs. There are other options, such as leveling via beast tribes and daily hunt bills. It's unavoidable when doing Mentor Roulette and quite confusing to adjust after each queue, but ultimately I inflict this on myself by doing it.
