When I first read the title it sounded liks some new sardonic slice of life RPG comedic Anime....but it wasn't.
As someone has already said, and I frequently point out in topics about damage meters and parsers, no amount of cajoling or nudging, or restrictions or tutorials will make players who don't want to improve, or don't see the need to improve, improve. It always comes back to this;
- Players that want to improve will improve, no matter what facilities the game offers - because they read their skill descriptions, listen to advice and try things out.
- Players that do not want or care to, will not improve, until such time as they want to.
- Nothing can change 1 or 2 above.
This seems to be a kind of mental blindspot in the FFXIV community in general. The perception that dungeons are easy as pie comes from being overgeared regardless of level sync, because both level and ilvl sync do not strongly enough nerf you, and in content with no sync, overgearing is horrendous.
The best examples are the original hard mode primals, specifically Garuda and Titan. Mention those now and people at like they are nothing but cake walks. Except that when encountered in 2013 with gear in the ilvl 60-80 range. The funny thing about it is that I just looked up a thread on a gaming site from then and someone is talking about requiring ilvl 90 gear, especially on DPS, for Titan. Titan was more about the AoE dance, tanks who knew how to handle Tumult and everyone making the DPS check during the heart phase. Of course back then Garuda got to deploy her mechanics before she was burned to the ground and the tank had to move her around the arena correctly to prevent the party wiping. But, with appropriate gear those fights were a challenge, and a lot of parties wiped, and ultimately needed the rather sad nerfs and Echo that were applied later.
But the point is exactly what you said "dungeons are easy because you are overpowered". Every time someone whines about dungeons being too easy, I think I will need to requote you, or at least paraphrase you.
