That´s actually the biggest issue. That 100 guys here or some streamer doesn´t represent the whole community. There are millions of players of players who were fine with certain class mechanics. Of course you can´t count voices, when nobody is saying a word. But it´s in nature of humans to stay silent if they´re staisfied and to moaning if something goes wrong.
We´ve elistists, decent players, casuals and completely noobs out there. Everyone has an own opinion and everyone should be catered in some way. I´m fine with it. But i´m not fine with the fact, that every subclasses are going to be the same. They could always go the way to pick one subclass for each category of gamers. A simple one for whose who can´t or don´t want to do better. 1 or 2 who have some unique mechanics. The last one could be way more complex to cater the upper 10% of players who enjoy more challenging classes. FF14 has enough classes to go that way, but no, everything is getting simplified until everything plays nearly the same.
Nocturnal might haven´t been always perfect, but it´s something which is up to the players decision. If someone doesn´t like it, why should it get removed? Just stay on Diu and let the players play Noc, who actually wants to play it. It´s not even a big work in the background since it´s implemented and SE just had to adjust some numbers here and there with new patches.
Btw we´ve a similar discussion in the DPS section already. This guy nails it in some way: https://forum.square-enix.com/ffxiv/...=1#post5502976
I personally can´t see the need of AST and SGE if we just get WHM 2.0 and SCH 2.0 with new animations and another gimmick, which is there just to create the idea/feeling of uniqueness, but isn´t one. (SGE and SCH can´t be played together anyway. If barriers can be stacked, then certain boss mechanics are going to get cheesed hard.)
