The general player base needs to improve

What you are suggesting is making the suggested newer Expert dungeons punishingly difficult right out of the gate.

Because punishing is the only way they get better. The way the difficulty is in this game in terms of individual mechanics means there is no gradual difficulty. There's no difference between an attack that lowers you to 50% HP for failng it, and one that lowers you to 1%. Both teach you the same lessons, the healer needs to recover you when you screw up, and dodging more or less is nice, but you don't die if you do and even if you do the healer will raise you. The fights that do teach you in the game have single, punishing mechanics that more or less wipe the party if one or more people fail them. Like if you don't sprint to the meteors in the chrysalis as a tank, everyone will die. If you don't position yourself perfectly from Rav's or titan's knockback moves you die and are out of the fight. But with Sophia you can literally die and fall nonstop; i cleared it with both white mages on the ground, 4 players, and me as only heals as rdm.

They'll seem punishingly difficult because to learn you really can't just keep having the healer fix your mistakes, nor the other dps carry you when you are on the floor. they probably will be a little less punishing than alte roite, who is pretty simple, but you need to have a mechanic like his where everyone has to go to their spots or they will die, and to a point the healer can't compensate for this nor the other member finish the instance.

You're saying gradual but in practice anyways it will be really hard.

And anyways, you truly only get better when you hit a wall and get mad/motivated enough to get over yourself and overcome it.
