Complex job still exists in the game.
Black mage is still there and other jobs that feels complete, such as GNB, DRG, SAM, NIN... Those are still in the game and have a nice balance between complexity and accessibility.
A dude with no fingers cleared TEA, everything is clearable by anyone given they have patience.
Do your mental gymnastic as much as you want, there is complexity in the game.
It's not trantrums or crying, it's called concerns. You are crying about players not agreeing with that direction so that everything remains accessible to you. You're rejecting every argument without logic, just going with the "muh game, raider bad

"
For myself I played MCH for 2 years, I did everything I could. If there is no evolution, I don't want to play the same job for another two years. I don't wish that feeling to anyone.
Raiders and casuals alike are like "I don't want to play with you anymore." when it comes to the job. Guess what will happen in two years? Casuals will move to the next shiny things.
